Dear Ning, Thankq.It is working now.iam able to save what i want. cheers MK On 4/29/05, Ning Yang wrote:

Bruce and Mahendra,

One thing I noticed before was if you want to save the sum(not fit) as a chi of K, you need to highlight both of the datafile (****.chi) and the "sum" and then click "save fit as". If either the datafile (****.chi) or the "sum" not highlighted, the sum won't be saved and the file has nothing inside. But this seems to be not true to the actual fit. You can always save the fit by clicking the same button no matter where the highlighted bar is.

Hope this help.

Mahendra,

I am forwarding your question and my answer to the Ifeffit mailing list. I recommend that you make use of that resource for your EXAFS and analysis software questions.

Once you make the sum of paths, you should find that, in the File menu, the menu item for "Save fit as" is enabled. I acknowledge that is somewhat confusing -- you made a summation, not a fit. But as far as Artemis is concerned, summations and fits are very similar. In any case, you can use that item in the File menu to save your summation in k, R, or q space.

There is a small bug in there. If you have not imported data yet, you can still save the summation in the manner I described, but the information written to the header will be incorrect. That will not preclude using the file, however.

Hope that helps, B

Dear Dr.Bruce Ravel, i am a new user of Arthemis. i calculated an exafs signal using phase and amplitudes calculated from Feff. i used the option "sum of paths(no fit)" in Arthemis. i am not able to save this as an ascii file. Please help me to go ahead. thanking you mahendra kumar
