Hi Bruce,
thanks for your response..I think that my problem is in the specification
of energy unit and/or the numerator/denominator. In the project I sent, I
imported the files specifying energy as "k" and nothing for
numerator/denominator. The plotter would then display the EXAFS as k2
weighted and I found that I couldn't change the plot display.
in a later attempt at importing data, I still specified energy as "k" but
then checked "chi" for the numerator. The result is still strange...the
data will be imported, but when I try to change k-weighting and replot, I
can't re-plot. I can plot the data in "R" or "q" space, but can't ever go
back to k...
anyway, here is the screen shot you requested. The data are sixpack
generated, I would think totally compatible.
thanks for the help, andrea

Andrea,
Your project file is horribly, unrecoverably broken. A project file in that state is unusual in the sense that I do not know how you got there and I do not know how to replicate it.
To understand what went awry, I would have to know more about how you got to that point. For starters, it would help to see the data that you imported into Athena to begin with. A screenshot of the state of the column selection dialog right before clicking the OK button would probably help also. I'll probably have more questions after that.
Bottom line, you found a neat, new (to me) way of breaking my program. Clearly the work of an experienced EXAFS person!! :P

Hello all,
I am an experienced EXAFS person, but not having a lot of luck using Athena.
I am trying to set up an Athena project for linear combo fitting.
I can get the data + model compounds imported, and I can save a project file. However, after saving and closing the file, the next time I try to open, I am asked to re-import the data from the project file (I think this is a normal part of Athena)... Inline image 4
...but when I try to select importing as chi(k) instead of u(E), I get the following message
This is certainly not related to the problem with the project file, but I want to point out that the box in the project selection dialog is labelled "Plot as", not "Import as". Its purpose is to display the data in different ways to help you decide what data you might want to import. Data is always imported from a project file in the same manner as it was imported from the raw data file regardless of how you choose to plot it before clicking the import selection button.

after "ok-ing" this message away, I can't get any farther. Importing the data as u(E) doesn't give the appropriate results.
I am also attaching the aforementioned project file.
thanks for any help with this, andrea
