2. Starting Artemis

The ARTEMIS program is launched on Windows by leftclick double-clicking the ARTEMIS icon on the desk top, by selecting artemis from the DEMETER menu in the Start Menu, or by typing dartemis (that's pronounced 'ɑ:rtɨmɨs, with a silent d) at the command prompt. If you installed DEMETER using the standard installer package, you can also leftclick double-click on an ARTEMIS project file (i.e. one with a .fpj extension) to open it in ARTEMIS.

On a unix computer, ARTEMIS is launched by typing dartemis in the shell. Depending on how DEMETER was installed on your computer, there may be some kind of application launcher, such as a desktop icon, a panel or dashboard launcher, or an entry in some kind of application menu.


Describe how this is done on a Mac...

Once started, ARTEMIS displays two windows, as shown below.


Fig. 2.1 The program, as it appears upon starting. The “main window” is the one accross the top of the screen. The “Plot window” is the skinny one on the left side.

Everything will certainly look a little different on your computer. This and all other screenshots in this document were taken on an Ubuntu Linux computer running KDE with custom window decorations. Although the details of the appearance may differ, all functionality is the same on all platforms. (You may not have a cool insect as the background image. Your loss.)

The window across the top of your screen is the “main window”. It provides an overview of the state of the program and of your fitting project. The window along the left side of the screen is the “Plot window”. It is used to control how certain plots of your data, fits, paths, and other things are displayed.

The plot window can be hidden by clicking the Plot button on the left side of the main window. Clicking that button again will make the plot window reappear in the same place on your screen.

The following two sections provide an overview of the functionality in these two windows. We will return these many times throughout this document.

Folders and log files

On occasion, it is helpful to know something about how ARTEMIS writes information to disk during its operations.

working folder

Many of ARTEMIS' chores involve writing temporary files. Project files are unpacked in temporary folders. The Gnuplot interface writes temporary files as part of plot creation. These files are stored in the “stash folder”. On linux (and other unixes) this is ~/.horae/stash/. On Windows this is %APPDATA%\demeter\stash.

log files

When ARTEMIS runs into problems, it attempts to write enough information to the screen that the problem can be addressed. This screen information is what Bruce needs to troubleshoot bugs. On a linux (or other unix) machine, simply run ARTEMIS from the command line and the informative screen messages will be written to the screen. On a Windows machine, it is uncommon to run the software from the command line, so ARTEMIS has been instrumented to write a run-time log file. This log file is called dartemis.log and can be found in the %APPDATA%\demeter folder.

%APPDATA% is C:\Users\<username>\AppDataRoaming\ on Windows 7.

It is C:\Documents and Settings\<username>\Application Data on Windows XP and Vista.

In either case, <username> is your log-in name.
