Yael, I don't quite understand this email or your original question, but it seems as though you're ok. It seems as though there was some confusion about how to use the column selection dialog. There is no scenario where Athena magically imports data without some interaction from the user. The user *always* has to select columns to indicate the energy column and to construct mu(E) from other columns. Even if one of the columns is already mu(E), it must be selected to that Athena know how to import the data. B On 03/02/2015 06:29 PM, kirshstein@gmail.com wrote:

Aha. so I kind of found a solution myself: the problem was assigning 1 and 2 when importing the spectrum. It wasn't clear to me that numerator had to be set to 1 when energy is column one. Now seems to work. Sorry to bother you. y.

Hello,

I have just installed Demeter and the first thing Athena does, when asked to plot (mu(E)) of an averaged standard spectrum (S-K-edge of CaSO4, averaged in sixpack), is to give the following error message: "Use of uninitialized value in multiplication(*) at C:/strawberry/perl/site/lib/Math/Spline.pm line 36."

Also E0 is 0 and in front of a red background. So it seems to have trouble finding E0. But why?

What does this mean? What do I have to do to get athena to work?

attached is the CaSO4 spectrum in question.

Thanks!
