Hello Matt and Bruce,

thanks for the immediate answers.

I think I now understand how to do that. Actually I did not want to 
change update_site to another website but to a local folder (is that 
also possible?) but if it is sufficient just to overwrite the 
installation directory with the content of the zip-files thats even 
easier for me.

I checked the batch file but both the shortcut to the batch file as well 
as the batch file itself seem to be correct. I also did a new 
installation from scratch but the situation didn't change. Here is the 
content of artemis.bat:

@echo off
SET IFEFFIT_MAIN=C:\Programme\Ifeffit
SET IFEFFIT_DIR=C:\Programme\Ifeffit

Immediatly after first start of Artemis the folder "C:\Program 
Files\Ifeffit\horae\stash\" is created where Artemis will store its files.
I found these entries in "artemis.config" (windows= obviously points to 
the folder that ifeffit actually uses):
windows=C:\\Program Files\\Ifeffit\\horae\\stash\\

Well, I have 265MB RAM. But it did work with the previous versions. 
These are the error messages when I try to start Athena when Artemis is 
running and vice versa:

I don't know myself.

Actually I do not want to edit the data. It just happened to me that I 
wanted to check if a data group loaded into athena corresponds to an 
experimental file, i.e. was read from this file (because I changed 
filenames afterwards).

I made a mistake in my previous posting:
athenatest.zip contains two experimental files: exp01.dat and exp02.dat 
with a (slightly) different scaling. I read them in and exported to 
exp01.xmu and exp02.xmu. The values indeed correspond exactly to the 
original files.
But if I import both groups to a single file then the scaling of the 
first group will be used for both and the ordinate data from exp02 will 
be changed accordingly. How is this done, linear interpolation?
Actually, I find this behaviour very useful: if I export many groups for 
display in an other program I can plot all of them versus the same 
abzissae-values. Is it possible to integrate that feature for export of 
single files as well? (as I now prefer that method because of the 
automatic parameter export).
