Hopefully this is not long winded, but I want to be as detailed with the problem as I can be. In the past, I have never had difficulty importing data into Athena, given it was formatted properly. It was working as recently as last night, but suddenly I have a problem today. 1. I open Athena 2. I go to File->Open Files 3. I click on the data file to bring me to the window where I choose Energy, Numerator, Denominator for the data and any reference spectra, etc 4. I choose the Energy, Numerator and Denominator This is when the first moment of "oddness" happens... I don't get a plot. Normally, I would get a plot of the spectra I am about to import to know if I selected the correct columns with the correct sign (and whether a Log is needed). 5. Confused, I continue anyway and import my choices. 6. I then get the following error from Athena: The following problems were found for group "Fe.060" 1 : The edge energy is unset 2 : The kmin for the forward transfer is negative (-2) You should fix these values before continuing analysis of these data. Note 1: I was trying with some old data that I have analyzed in the past from Athena through Artemis and know to be okay for analysis. Note 2: I then tried studying some MnO spectra by importing that data taken during the 2011 XAFS Summer School in Chicago taken from APS. I know these text files to work, as we looked at them AT the summer school. Note 3: As a last resort, I tried downloading the Fe example from the Athena website (as you can see above from Fe.060), but it can't even read this in. Note 4: Athena CAN open old projects where the data was already imported without problems... it just seems I can't start a new project and import data into it successfully. I have tried searching all through the internet for anyone who had the error above or my difficulties to no avail. I have tried making sure the line breaks were correct by resaving data into new files through textwrangler and even going through vim in a terminal, to no avail. Note 5: As a last resort, I reinstalled iXAFS, but this hasn't fixed the problem. Anyone have any suggestions? Am I suddenly forgetting a step in the data import process?
