Hi Danilo,

Dear list,
I have a big collection of data from a catalytic reaction. I tried to export all the spectra (about 200) to a unique file containing the normalized ones. I used the "File>Save marked groups as>norm(E)" option. Unfortunately, Athena (Demeter 0.9.18) is not able to make one unique file (it crashes and I have to initialize it again), instead I had to creat 4 different files of 45 spectra each (the maximum group I could gather on a file). Is there any bug on it or some kind of limitation to creat these kind of files?
Best regards,

This is sort of "known problem". That is, we know that there will be some threshold where the underlying ifeffit engine will run out of memory, way before any reasonable laptop being used today would actually be short of memory. I can't say that we know that 200 spectra will never work, or that 45 will always work, it depends on the size of the arrays and how much processing you've done on the data. The problem is effectively removed with Larch, the next generation of the Ifeffit engine. I know Bruce is working on (and making progress on!) having Athena use Larch, which will be particularly useful for handling large data sets. For now, I think you're sort of stuck with having to grup the data as you are doing. As always, any help on Larch and Demeter would be greatly welcome. -- --Matt
