[Ifeffit] Importing Multiple Data Sets into Athena

[Pruessmann, Tim (INE)]

Hi Dan,

I had the same problem recently. It can be avoided by importing each scan seperately.

Hi Scott,

I have attached 3 of the data files and the Zr foil ref scan (already calibrated). I first import the reference Zr foil scan and then the 3 files. 
The Numerator for the data is column 30 and i also import the ref channel where the numerator is column 7. If i choose to set ref to standard values (as you would expect that to work) it fails and makes processing difficult. 
The only way round it i see is to import each data set individually and set the element, edge and value of E0 manually (for the reference - the data is read correctly) before then using the "align marked groups" function to align all the data to the standard Zr foil i imported at the start.

Having played with the setting on the preprocess tab if you check the "align to standard" radio button it aligns the data (not the reference channel) despite the fact the "same element" radio is not checked - should the preprocessing not apply to the reference channel (if present) before the data channel?

As i say it is not a huge problem and i only report it in the interest of bug removal.

Thanks,
Dan
