1.1 0.9.26 ?? April 2017

1.1.1 Athena

  • fix XDI headers in “save marked groups” output files, also add templates to provide for the special case in k of two abscissa columns
  • Boxcar average smoothing failed to copy bkg_eshift to the new group (Thanks to Ian Godrey) Fixed same error in Gaussian filter smoothing.
  • Fixed a spurious error message reporting results of an LCF fit. (Thanks to Fred Mosselmans)
  • When doing things with marked groups in diff spectrum tool, be sure that standard is removed from the list of marked groups. (Thanks to Sinead Rowe)
  • Fix a problem processing keV data when using Larch (Thanks to Juan de la Figuera) (See issue #42)
  • Bug fix for the SSRLA filetype plugin (Thanks to Simon Bare)
  • The check for exceeding Ifeffit’s rough limit was ridiculously broken

1.1.2 Artemis

  • Actually use the user-supplied value of epsilon_k (Thanks to Victor Streltsov)
  • disable C-left on path list, which was used (I think) to clone paths. This is a loss for dnd a path to another data set, but I suspect that is not much used.
  • Fix several bugs in multiple data set fits using Larch
  • Change the symbol for an excluded path from three parens (((path))) to --(path)--
  • Improved validator for N path parameter – it can now be blank. Also selecting all then typing works sensibly
  • Put in a more rigorous check for exceeding &max_data_sets when using Ifeffit. Simply refuse to import more than that many data sets regardless of Include in fit settings. (Thanks to Victor Streltsov)
  • Fix a bug finding location of gnuplot and feff executables (Thanks to Robert Gordon)

1.1.3 Atoms

1.1.4 Hephaestus

  • Added P K, S K, Cl K, Ag L3, and Pb L3 standards contributed by Lisa Bovenkamp-Langlois

1.1.5 Demeter

  • Try to start Larch, if no success fall back to Ifeffit. Accept a PR from Matt related to this.
  • Delay loading of more stuff to speed start-up
  • Update non-root installation instructions (Thanks to Patrick Browne)
  • DEMETER_MODE and DEMETER_NO_BACKEND environment variables recognized. The first provides a way to set the Mode ui very early in startup. The second blocks using either Larch or Ifeffit for an application that is entirely contained within Demeter (WebAtoms, which does not plot, is an example).
  • Recognize and use web import mode, i.e. use Demeter qw(:ui=web);
  • Attempt to teach STAR::Parser to deal with “_eof” in a CIF file. (Thanks to Alessandro Longo)
  • Fixed a few testing bugs, skip XDI tests, force use of Ifeffit for testing. The last two are not permanent. In particular, testing with Larch is very important.
  • All tests passing with Larch (also still pass with Ifeffit)!

1.1.6 Windows

  • Fixed missing columns from mu(E) and norm(E) output files for XANES data (thanks to Jeff Catalano)
  • Fixed a problem with selections in data summer being unset in certain situations (thanks to Ian Godrey)
  • Offer a useful warning when trying to read an Artemis project file into Athena (thanks to Galen O’Neil)
  • Add filetype and beamline plugins related to BL8 at SLRI (thanks to Wantana Klysubun for beamtime!)
  • Fix display issues in peak fitting tool, use three-letter strings rather than numbers as identifiers, discarding works better, action buttons disabled when last function is discarded (thanks to Wantana Klysubun and the participants of the 2016 ASEAN Workshop on XAS)
  • persistence in project file for LCF, PCA, peak fit (thanks to Sunil Patil) works for both original and JSON style project files
  • Plot indicator in MEE tool

  • Now using gnuplot 5.0.0 in the Windows installer

1.6 0.9.21 26 February 2015

Begin practice of using {preN} tags to indicate exactly when a feature was added. Also begin practice of acknowledging the (appropriate individual) directly with the change log entry.

1.6.1 Athena

  • XDI integration (available in Demeter, but Xray::XDI is not currently in the Windows distribution)
  • pluck button for MEE
  • fixed a bug related to the inv button in Col Sel dialog (thanks to Ian Rosbottom)
  • Fixed the appearence of the Busy cursor in column & project selection dialogs on Windows (thanks to Ian Godrey)
  • Improvements to import of chi(k) data + LCF using chi(k) imported data (thanks to Andrea Foster)
  • Menu items for reporting a bug and asking a question
  • Add energy columns to chi(k) output files. (thanks to Karina Mathisen) {pre3}
  • Take care to handle xdifile Data attribute when Xray::XDI is not available (thanks to Ian Godfrey) {pre3}
  • Fixed faulty output file from log-ratio analysis {pre5}
  • Fixed a problem whereby a group using a bkg removal standard not present in the project would cause a crash (thanks to Allen Robert Morris)
  • Option for writing and reading Athena project files in a JSON format. (thanks to Matt for the prompt)

1.6.2 Artemis

1.6.3 Atoms

  • Menu items for reporting a bug and asking a question
  • slapped an eval around the feff run. this allows feff to fail a bit more gracefully. feff’s error message gets sent to STDERR (i.e. the screen or the log file on Windows) and an inscrutible message gets posted via carp, but Artemis/Atoms does not crash. (thanks to Stephen Parry) {pre4}

1.6.4 Hephaestus

  • Menu items for reporting a bug and asking a question

1.6.5 Demeter

  • Expunge all reference to my email address, replacing it with a link to my homepage
  • Work around the mysterious situation on Windows wherein the MRU file gets overwritten with a few hundred NUL characters, causing a crash in Config::INI::Reader. I have no idea what causes this, but changing from croak to carp when handling an unparsed line avoids it and issues a useful error message. (thanks to Kurinji Krishnamoorthy)
  • XKCD-ish plots in A&A
  • font picker control now available in Demeter::Wx::Config
  • Update tests to reflect recent larch-related changes (thanks to Stevan Ognjanovic)
  • Fix a silly mistake introduced to one of the Chantler data files when I did s{2014}{2015}g in January (thanks to Stevan Ognjanovic)

1.6.6 Larch

  • Much work on both Athena and Artemis to work properly with Larch, particularly in light of recent changes to larch server
  • Made “l” versions of A, A, and H. These set DEMETER_BACKEND to “larch” in the BEGIN block
  • Made larch_server.ini file, specify windows path for larch_server

1.6.7 Windows

  • Add Demeter version number to screen/log file messages {pre3}

  • Control-left-click for reorganzing group list items disabled in favor of file drag-n-drop
  • Booth self-absorption algorithm now implemented correctly
  • Added Hephaestus doc to the Athena Users’ Guide
  • remove coloration characters when saving the contents of the status bar buffer so as not to trigger perl’s wide character warning
  • error messages for zero plotting range, excessive columns in save marked groups with Ifeffit, and lots of groups with Ifeffit

1.7.2 Artemis

  • Drag and drop Athena or Artemis project files onto the Data list
  • Drag and drop CIF, Atoms, Feff input files onto the Feff list

  • fixed problems handling import of chi(k) data into Artemis
    • fixed a problem serializing data that had been imported as chi(k)
    • take care to toggle the from_yaml attribute to true when importing data from a project file. this was needed to pass the “data exists” fit sanity check
  • corrected an odd bug whereby relation between a FSPath and it’s Feff calculation could be lost in a project file (see thread starting at http://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg04288.html)
  • save path interpretation from Path page in Atoms window
  • reorganized some buttons in the Atoms window

  • fixed a bug related to importing a feff.inp file directly onto the feff page in the Atoms GUI
  • import buttons on Atoms and Feff pages respond sensibly to files that are not CIF/atoms or feff files
  • enable aggregate calculation (given that paper will be accepted for publication by the time this is released), but only for Atoms in Artemis, not for stand-alone. Wrote documentation page for aggregate calculation
  • put controls for degeneracy margins front and center
  • deal sensibly with Feff’s hard-wired maximum cluster size of 500 atoms by writing only the first 499 sites, regardless of how many atoms are within Rmax
  • somehow, the shift vector never got implemented in Demeter (even though there are controls for it in the Atoms GUI). Wow! That is now fixed.
  • fixed a mistake reading space group symbols from CIF files when an alternate orthorhombic setting was used in the CIF file
  • progress on getting Atoms and the GUI to work correctly with rhombohedral groups
  • new button in GUI for inserting shift vector from Int’l tables

  • escape backslashes in filenames before sending them to Larch

1.7.6 Demeter

  • lots of code clean-up
  • improved methodology for populating Config pages in the GUIs

  • keyboard shortcuts for merging (C-S-m, C-S-n, C-S-c for merging in mu, norm, chi)
  • right click on several plot buttons makes a special plot from the Plot menu + status bar hints
  • added “Shrink” to plot options. this hides the k-weight and plot options controls, allowing more room for the group list. also shows a button for restoring the k-weight and plot options controls
  • added “Show measurement uncertainties” submenu to Group menu with options for this, marked, and all

1.8.2 Artemis

  • Fixed a bug in SSPath creation by drag-n-drop from pathlike tab
  • Add a site button now working on Atoms page
  • Graceful failure and useful warning message if crystal data results in 0 scatterers

  • Deal better with a project file saved before performing a fit
  • A bit more control over labels in path list with artemis->feffpathlist config parameter
  • Athena file MRU list now remembers record number and defaults to that record when selected
  • fixed a bug resulting in repetitious display of parameter values in log file
  • save VPaths to and restore from Artemis project files
  • added “transfer all” button to VPaths tab in Plot window

1.8.3 Atoms

  • fixed a bug processing hexagonal and trigonal groups with the command line atoms. oddly, these were handled correctly by the Wx version

  • use path ranking choice to make intrp and display all rankings from button on intrp page

1.8.4 Demeter

  • Made the Demeter::Feff::Aggregate object for performing the pathfinder fuzzily over multiple crystallographic sites.
  • Addressed some failed tests in 012_atoms
  • Fixed a problem with fixed edge step value and XANES data
  • Added plus/minus sign to Demeter::UI::Wx::SpecialCharacters
  • Require MooseX::Types::LaxNum since Moose now has a much more strict definition of Num in a type constraint.
  • Fixed an issue surrounding Plot object’s terminal_number parameter and pgplot
  • Fixed a bug in the filetype plugin for the Lytle database
  • Require Archive::Zip >= 1.31 to get the option of Archive::Zip::UNICODE=1 which should help computers with unicode language settings
  • Implement Karine Provost’s path ranking criteria

1.8.5 Windows

  • New installer package with perl 5.18.1 and most recent versions of all dependencies

  • Andrei Shiryaev and Fen Fen Zhu noticed that unicode in Artemis project files was problematic and Matt Newville suggested a solution
  • Denis Testamale noticed that test 012_atoms was failing
  • George Sterbinsky for noting that a fixed edge step value was not respected for XANES data, for noticing the problem renaming Athena group names, and for noticing numeric type constraint issue with Moose>=2.0900.
  • Eric Breynaert for noticing a crash after discarding a Feff calculation
  • Julius Campecino for noticing an inelegant handling of a situation where running atoms results in 0 scatterers
  • Karin Provost for the idea of path ranking
  • Daniel Olive and Corwin Booth for pointing out that the Booth self-absorption implementation was horribly flawed

1.9 0.9.18.3 28 January 2014

This is a branch created to facilitate development of the Macports package. It has the following changes:

  1. Remove the dependence on Wx::Html and Wx::HtmlEasyPrinting, which is my suspect for the source of the seg fault
  2. Backport a requirement of MooseX::Types::LaxNum from 0.9.19. This solves a problem resulting from a recent change to the Moose object system, which Demeter relies upon.
  3. Backport from HEAD the use of Wx::LaunchDefaultBrowser in Hephaestus. This removes the need for Wx::Html and uses the system browser to display the documentation, which works in Athena.
  4. Adds the CPAN modules MooseX::Types::LaxNum to the requirements in Build.PL
  5. Backports from HEAD a page in the Athena Users’ Guide and several image file so that Hephaestus has something to show in the browser
  6. Backport from HEAD the changes to the datoms script

  • Calculation of approximate uncertainty in edge step
  • Set E0 of all/marked groups using an algorithm, see Group menu
  • Added a specified multiplicative constant in the column selection dialog and its persistence file
  • Fixed a column selection bug: when importing multi-column data with the each column button ticked on along with a reference spectrum, each group (one per column) will get a reference spectrum. The reference is now cloned for each group. Previously, each reference group pointed at the same Ifeffit data group. Removing one reference group from an Athena project would remove the Ifeffit group, leaving the remaining copies unplottable. By cloning, the reference groups are now completely independent.

  • added the fit -> zeros template to correct a problem importing a project with a fitting model but no fit
  • Demeter::UI::Artemis::ShowText now has a save button
  • added EdgeStep recipe
  • plot margins
  • Diff object, flags for disabling integration + setting datatype, use indicators rather markers in plots

  • Fixed behavior of up arrow for Athena’s string entry dialogs that have buffers. The first time pressing up arrow went to an unpredictable part of the buffer. It now will go to the most recent entry.
  • Force dk and dr to 0 when making empirical standards.

1.20.2 Artemis

  • Display a useful error message when the phase.bin file is not computed correctly. Also clear and do not display intrp tab.

1.21 0.9.9 20 April 2012

1.21.1 Athena

  • Delay laying out most windows until needed for the first time. This speed up startup at the cost of a bit more time later on. Start-up went from about 6 1/2 sec to under 4 seconds on my work computer
  • Mostly functional file watcher + added functionality to IO methods
  • Importance was not being imported from a project file
  • Made the importance control normal width
  • Added athena->interactive_fixstep configuration parameter for disabling the interaction between pre-edge, normalization, and edge step controls and the fixstep button.
  • when importing a sequence of files and one cannot be imported (e.g. aborted scan) offer to continue or quit importing sequence
  • XDI as a known file extension when importing data
  • Importance and plot_multiplier functionality for bent Laue data from 10ID
  • Return to main button was being displayed incorrectly
  • Found a normalization bug in Ifeffit, norm_order not respected in call to spline(). Submitted patch to Matt.
  • Smooth works in Calibrate tool

  • Display of peak fitting page is functuional (but not quite right) even on Windows.
  • Fixed a column selection bug involving the “import each channel” button
  • Edge step was not reliably updated after a new plot

1.21.2 Artemis

  • Fixed (mostly) a bug laying out Atoms/Feff notebook tabs when importing a project file.
  • Fixed a sanity check that got incorrectly triggered when replacing data with the same data (for example, after going back to Athena to adjust E0)
  • Fixed a problem displaying the new name in the hide/show button when replacing a data group

1.21.3 Hephaestus

  • Delay laying out most windows until needed for the first time. This speed up startup (~6 1/2 seconds before, now just under 3 second) at the cost of a bit more time later on.
  • Fixed a bug in furmulas tool where missing density caused a divide by zero crash

1.21.4 Atoms stand-alone

  • Used delayed layout and careful loading of Demeter modules to reduce start-up from over 5 sec to under 3 seconds.
  • Fixed a bug reading a CIF file that does not properly identify the material. This resulted in the record selection dialog being posted without any content – not so helpful.

1.21.5 Demeter

  • Begin using Perl::Version to manage version numbering of files and brought every file up to 0.9.9
  • Replaced Readonly with Const::Fast. See http://neilb.org/reviews/constants.html
  • Abstracted many common constants to Demeter::Constants
  • Replaced Config::IniFiles with Config::INI for a small performance improvement
  • Made Demeter::IniReader, a subclass of Config::INI
  • Fully deprecate use of MooseX::AttributeHelpers and remove it as a dependency
  • Make https://metacpan.org/pod/File::Monitor::Lite a recommended module (for data watcher)

  • Take care not to “use Demeter” unless absolutely necessary throughout code base
  • Deal with Unity’s use of a global menu
  • Many improvements to histogram subsystem
  • Added a Build directive for forcing update to ifeffit wrapper
  • Cut >20 seconds off the running of the test suite by correctly using import “pragmata”
  • Implemented frozen groups as an attribute trait which silently disables setting an attribute – see MooseX::Quenchable. Implementing it this deeply in the underlying object obviates the issue of disabling Athena’s various “action at a distance” features, e.g. constaining parameters.
  • Fixed a bug whereby a group with datatype of xanes did not have its normalized derivative and second derivative spectra calculated.

1.22 0.9.8 30 January 2012

1.22.1 Athena

  • Only set project name if the project name is unset and an entire project file is imported

1.22.2 Artemis

  • Can now export a particular fit from the history to an fpj file
  • Fixed a bug repopulating the recent files menu
  • Fixed a bug in which the <data>.fit file was deleted as a project was imported. This was the main reason the history plot tool was broken.

1.22.3 Demeter

  • Added a tool for efficiently merging a large number of data files, see Demeter::Data::BulkMerge
  • Added denergy script

1.23 0.9.7 12 January 2012

1.23.1 Athena

  • Fixed a problem in the X23A2MED plugin – it was getting confused by an incomplete set of (roi, slow, fast) columns.
  • Fixed a bug resulting in bkg_fixstep sometimes getting unset when plotting multiple groups
  • Constraining “Current group” parameters via context menu now works correctly. It had mistakenly changed group attribute, a very dangerous thing!
  • Extensive support for current XDI draft
  • In column selection dialog, change reference radio buttons to checkbuttons so that either numerator or denominator can be unselected.
  • In column selection dialog, unchecking reference ln button triggered a crash.
  • Fixed incorrect color sequence for marked group I0 plot. This also made marked group I0 plot crash with >6 marked groups.
  • Post busy cursor when closing a project
  • Reorganized Monitor and debug menus

1.23.2 Artemis

  • New icons!
  • Added preview and print buttons to log, history log, history report, and journal

  • fixed a bug causing a segfault when discarding data or feff
  • capture Atoms’ statusbar messages in Artemis’ status buffer
  • Faster project file import using partial deserialization of each item in the fit history. However, history plot tool is not currently working.
  • Reduce R-factor penalty by factor of 10 when fitting in k-space
  • Can now restore a previous fit reliably.

1.23.3 Demeter

  • explicitly unset xrange at the start of every gnuplot plot. this should fix any problem where zooming results in a backwards x-axis.
  • added clear_ifeffit_titles method to clear out $group_title_NN strings when no longer needed, use wrap to make this more efficient
  • bkg_eshift was not applied when saving a group as mu(E) or norm(E)
  • serializing Atoms object made safe for GUI display of object contents
  • Mechanism for associating metadata with files imported using a plugin

1.24 0.9.6 12 December 2011

1.24.1 Athena

  • Fixed bug preventing import of multiple files with each channel as a separate group
  • Fixed a bug in which importing MED data as separate groups failed to initialize data processing parameters
  • Update column selection dialog when switching from eV to keV units
  • Handle keV units correctly for data and reference
  • Handle very noisy reference data by setting the default E0 to the tabulated value if the ifeffit-found value is far from the e0 of the associated data. This is essential for data that needs rebinning.
  • Correctly handle the situation where a column data file has a column named “xmu”. Previously, that situation could lead to data being corrupted in an unrecoverable manner as the column selection dialog uses that same suffix to hold the mu(E) data. This is done by constantly rereading the data file – something that will not happen (happily, since doing so is slow) for any file without that column label.
  • Added functionality to column selection dialog for bulk (de)selection of numerator checkboxes and for pausing the replot of the data while selecting columns (all of which may be useful for an MED file)
  • Do some sanity checking on Rebin values in column selection dialog before actually rebinning
  • Fixed a bug in both Plot->marked groups menu options

1.24.2 Artemis

  • Trim leading and trailing spaces from gds names.
  • Write parameter history reports correctly.
  • Improved window management. Showing and hiding windows now works correctly in conjunction with the window manager’s minimize (iconize) function.
  • When right clicking on a word in a path parameter math expression to define a parameter, the value is now sensitive to which path parameter the work comes from (s02 -> 1, sigma2 -> 0.003, else 0)
  • Fixed a windows only bug – when a feff.inp file is imported, the Atoms tab is supposed to be disabled, but the mechanism I used to disable selection of that tab was guaranteed to fail on Windows (see http://docs.wxwidgets.org/2.8.4/wx_wxnotebookevent.html#wxnotebookeventgetselection)

1.24.3 Hephaestus

  • Allow floats as values in the ion chamber tool

1.24.4 Demeter

  • Check that user value, then default value of executable path (i.e. gnuplot and feff) actually exists before attempting to run them. Also properly quote executable name in system call or pipe so that things like spaces and parens are interpeted correctly. This guards against a number of issues. If Demeter is installed on Windows in one location, then unistalled and reinstalled elsewhere, the ini file will retain the incorrect value. This also guards against having an executable in a place with somethinng like “system (x86)” or a unicode character in the path.
  • Begin playing around with using Demeter::Return as a function’s return value (see rebin_is_sensible in Demeter::Data::Process
  • Explicitly reset xtics when starting a new plot with gnuplot. This is necessary because the components plot afetr a fit sequence specifies an array of xtic labels.
  • Prefer the Pd K edge to the Bk L2 edge when finding the edge
  • Set bkg_pre2 to a value which is sensitive to the edge energy. For higher energies (i.e. broader edges) move bkg_pre2 to a lower energy to improve the default pre-edge line
  • Do a better job of recognizing as data are imported whether an energy array is in keV units
  • Filetype plugin written for ESRF BM23, which uses a single scan SPEC file.
  • Added rebin->use_atomic configuration parameter
  • Added a filetype plugin for data from the old SRS. This is intended to cover data from DUBBLE as well (thus deprecating the DUBBLE plugin).
  • Test to see whether local time can be used in Demeter’s now method. Using local time will make a program die if the computer's time zone is not set. The fallback is to use DateTime's floating time zone.
  • Fixed 2 tests in the test suite to respond to recent changes to the alignment algorithm and the Fit object’s fetch_gds method
  • Correctly identify files as being not data in the case where it nominally looks like data (i.e. it has a header and column labels as Ifeffit expects), but which has 0, 1, or too few lines of data
  • Made file->minlength configuration parameter to define “too few” points in a data file.

  • Better first guess for autoalignment ($DS->bkg_e0 - $D->bkg_e0)

1.27.2 Artemis

  • Fix a problem importing a project file into which data and Feff have been imported, but no paths have yet been assigned to any data
  • Check parameter types when importing GDS parameters from a text file

1.27.3 Demeter

  • Added current attribute to Mode as a way of identifying data groups in asequence when making progress messages in a GUI

1.28 0.9.2 7 November 2011

1.28.1 Athena

  • Preserve source attribute when reading a project, display it as a mouseover for file TextCtrl
  • Plot after pluck
  • Bigger Rbkg control
  • Added some Athena config parameters
  • Fixed a problem with DUBBLE plugin

1.28.2 Artemis

  • Fixed spurious creation of feff workspaces when importoing FSPaths from a project
  • Begin work on making Artemis/Atoms fail gracefully with CIF file that trigger problems. Here, it fails gracefully for CIF files with partial occupancy.
  • Store parameter and path evaluations in the Fit YAML so that fit history can be correctly reconstructed. This has the drawback of breaking old fpj files, in that they will no longer display correctly in the history. Oh well….

1.30 0.9.0 31 October 2011

This is substantively identical to beta release 9. This initial release will be announced broadly on the mailing list and will be used at the XAS course at Diamond, Nov. 14-16 2011.

Path to 1.0:

  1. A few successful months of use
  2. PCA, peak fitting, LCF fully implemented in Athena
  3. Histogram fully implemented in Artemis

1.30.1 Artemis

  • Verify that fit folder exists before trying to deserialize it

2 Beta testing releases:

2.1 Release 9: 30 October 2011

2.1.1 Athena

  • Display YAMLs for PCA and PeakFit objects
  • Fixed a bug using one of the self-absorption algorithms
  • YAML displays in Athena for PCA and PeakFit objects

  • it was possible to drag and drop non-numeric text onto the N TextCtrl
  • Prompted to save current project if importing a project while there appears to be a project started in Artemis. The current is saved or not, then Artemis is cleared, then the new project is imported.

2.1.3 Demeter

  • Atoms cluster list now tags atoms by shell
  • Forcing display of debug menus in A&A until they become more stable
  • Added a recipe for using Empirical standards
  • override all method in Demeter::PeakFit

  • use Demeter::FPath so that empirical standard can be written
  • fixstep button was being erroneously ticked due to a bug in pre/norm/step interaction
  • ignore project file records that are malformed due to missing data arrays
  • resort data if energy column other than 1 is selected in any way when using the column selection dialog

2.2.4 Acknowledgements for this release

  • Fred Mosslemans
  • George Sterbinsky

2.3 Release 7: 10 October 2011

2.3.1 Athena

  • Handle changes to rmax_out correctly
  • Handle the absence of PDL more gracefully
  • Implemented peak fitting tool
  • Fixed a bug that was slowing down the response of the column selection dialog
  • Fixed a bug causing a crash when importing keV data
  • Fixed display of ISO-8859 encoded data files in the column selection dialog.
  • Attempt to deal more gracefully with unreadable files

2.3.2 Artemis

  • Fixed a formatting error reporting correlations in the log file
  • Changed the logic for how GDS params get updated before a plot
  • Issue Ifeffit’s unguess command at the beginning of a fit to make sure that discarded or skipped (or def-ed or set) guess parameters do not remain as guesses in Ifeffit, which makes it impossible to evaluate uncertainties.
  • Fixed a bug in how the pathfinder->label configuration parameter was being interpreted. Also changed the default absorber token to @
  • Handle changes to rmax_out correctly
  • Fixed a bug importing projects from earlier versions of Artemis (deprecated nindicators attribute of the Plot onject)
  • Quick first shell (FSPath) now properly respects a change in N
  • Fixed a bug wherein Artemis would crash reading a project file with a quick first shell (FSPath) object
  • Implemented drag-n-drop for cloning a path and copying a path to other data sets
  • Fixed a bug cloning quick first shell (FSPath) objects
  • Artemis now respects choice of fit space.
  • Right click on words in path parameter math expressions to post a context menu for creating/modifying GDS parameters
  • Fixed a bug precluding creating an atoms.inp by hand via the GUI

2.3.3 Demeter

  • Fixed a problem interpreting rhombohedral space groups in Atoms.
  • Implemented peak fitting using Ifeffit as the backend (other option is fityk)
  • Files with very wide column label lines can run into a length limit in Ifeffit, specifically in ishtxt iff_show.f. Since Demeter relies on Ifeffit reporting $column_label correctly, this lead to truncation of columns available when importing such data.
  • Made the save_many and save(“fit”,…) methods understand either set of strings denoting the part to be saved. (save_many took things like ’chik2’ and ’chir_mag’, which save(“fit”,…) took things like ’k2’ and ’rmag’). Also added a useful error message to save_many warning against passing it ScatteringPath objects.
  • Improvements to the Dubble plugin
  • Fit sanity check: notice an obvious case of attempting to use the same data set more than once in a multiple data set fit. This is presumed to be a naughty attempt to increase Nidp.
  • Inverted residual function in PCA plots
  • Fixed several bugs importing already-normalized data
  • Added Encoding::FixLatin as a dependence. There is some chance of data corruption using this tool, but since it is only used for display of text in a GUI and not for passing data to Ifeffit, this is not a very serious problem.
  • Fixed a bug wherein a cloned Data group did not have its derivative computed
  • Fixed a bug in aligning data. Also modified code to perform alignment exactly like the old version. Made “interp” the default interpolation function (was qinterp).
  • Found a few places where files or directories were opened and not closed
  • The element symbol type constraint was missing Am through Cf
  • New “trace” method for printing a colorized stack trace from any location to stdout
  • Fixed a bug in the automated alignment algorithm (now using data’s current bkg_eshift as the initial guess)

  • Added a fourth plotting terminal
  • Issue error to statusbar when kmax_suggest is oddly small
  • Implemented Scott’s deriv(phase(chi(R))) idea with a configuration parameter for turning it on and off
  • Copying a group now copies its marked state
  • Added invert button to column selection dialog
  • Implemented PCA tool
  • Commented out Freeze menu since group freezing is currently unimplemented

2.4.2 Artemis

  • Added a fourth plotting terminal
  • Make the import file menu entry recognize all plausible file types and do the right thing. This makes the Import submenu somewhat redundant.

  • Allow seeting window function for back transform independently
  • Fix default settings for LCF object in athena’s LCF dialog
  • Tie together merge and reference for merge when the reference for the merge is also made
  • Added a “change all groups” option to the chnage type dialog
  • Made the LCF layout a bit prettier
  • Do not unlink autosave file at start-up – it needs to stick around in case the problem that lead to the crash happens again
  • Improved behavior for Copy group feature

2.5.2 Artemis

  • Allow seeting window function for back transform independently
  • Fixed a bug involving non-zero values of arbitrary k-weighting when importing old-style project files

  • Inmplemented an autosave feature + recovery of autosave after a crash
  • Fixed several LCF bugs
  • Use arbitrary k-weights more sensibly
  • Fixed a bug plucking spline range in k
  • Better message in pluck dialog
  • Use demeter’s configuration dialog to configure Plugins that have configuration parameters (currently, 10BMMultiChannel and X23A2MED)

  • Replacing chi(k) on a Data frame now works correctly
  • More descriptive update messages in statusbar during histogram processing
  • Histogram interface is more sensitive to whether time-consuming chores need to be redone
  • Grid in GDS frame now recognizes smart keys for changing parameter type. Change all selected params:
    • Alt-g: guess
    • Alt-s: set
    • Alt-d: def
    • Alt-l: lguess
    • Alt-k: skip
    • Alt-a: after

  • Follow Windows link files for various import types
  • Check file type on import for:
    • fitting projects
    • Athena projects
    • old-style fitting projects
    • demeter serializations
    • chi(k) data (this is imperfect – mu(E) data, for instance,will pass the test)
  • Use arbitrary k-weights more sensibly

2.7 Release 3: 8 July 2011

2.7.1 Athena

  • Plugin registry: right click open a menu with for plugin documentation (POD converted to text, displayed in a Demeter::UI::Artemis::ShowText) and a configuration utility for those plugins with an ini file.
  • Fixed several problems with the automation of the column selection dialog
  • The X23A2MED plugin now configures itself on the first use and responds gracefully to misconfiguration. It also handles data from the 1-element Vortex.
  • Pluck buttons implemented in more places
  • Merging groups with reference channels also merges reference channels into a reference group for the merge
  • Tools for monitoring Ifeffit’s memory use
  • Modified SSRLA plugin to handle data from the ESRF ROBL beamline. ROBL writes some high-ASCII characters in a way that confuses the column selection dialog, so theplugin strips them from the file
  • Athena is now capable of following windows shortcut (.lnk) files

2.7.2 Artemis

  • Pluck buttons now work on the Data page and on the indicators tab

2.7.3 Demeter

  • Changed the default color of indicators to a dark brown, which stand out better against a red trace (i.e. line color #2)

2.7.4 Windows installer

  • This time I really made it so that all bat file launchers save STDOUT and STDERR from the current session to a log file in %APPDATA%\demeter\
  • Make %APPDATA%\demeter\ at install time if it does not already exist
  • Compile Ifeffit with an 8 Mb heap, more arrays, and more Feff paths.

2.7.5 Acknowledgements for this release

Same gang as last time + Stephen Price.

2.8 Release 2: 24 June 2011

2.8.1 Athena

  • Fixed some language issues in the Files menu
  • Fixed several bugs surrounding the bkg_fixstep Data attribute and made its behavior in relation to editing the normalization, pre-edge, and edge step text entry boxes more sensible
  • Added wxTE_PROCESS_ENTER style to all text entry boxes. This allows replotting or other actions (or none at all) upon hitting return with focus in a text box. This is in response to a complaint that hitting enter in a text box caused focus to shift unexpectedly and to a request for more functionality.
  • Rewrote the quad plot
  • Clarified language used in stack tab of plotting options section
  • Fix a problem doing LCF fits with the final weight being negative when weights constrained to be non-negative and to sum to one.
  • Escape underscores in gnuplot plot legend for LCF plots
  • Fixed a bug using a background removal standard
  • Athena now reads chi(k) data files correctly
  • Group list:
    • Control-drag to rearrange groups in group list
    • Ctrl-j/Ctrl-k to change focus up and down in the groups list
    • Alt-j/Alt-k to move groups up and down in the groups list
  • Work around spurious error message when plucking from Gnuplot on Windows
  • Multiple plotting terminals with Gnuplot
  • Configure utility for filetype plugins that come with configuration files

2.8.2 Artemis

  • Completely rewrote mechanism for importing old-style Artemis project files, which now works much more reliably.
  • Feff object’s rdinp method now recognizes a Feff8 input file. This is mostly used by Artemis to refuse to import such a thing as Feff8 is not yet supported in Demeter
  • Implemented Rk plot and made a button for it
  • Added wxTE_PROCESS_ENTER style to all one-line text entry boxes.
  • Multiple plotting terminals with Gnuplot

2.8.3 Demeter

  • Changes to selection of the plotting backend just prior to R1 broke most of the tests. Both the selection mechanism and all the tests were fixed.

2.8.4 Windows Installer

  • Renamed desktop icons so as to not overwrite Horae’s icons
  • All bat file launchers save STDOUT and STDERR from the current session to a log file in %APPDATA%\demeter\
