Dear Matt, Thanks for your answer! I tested the same .cif on another computer and works fine, even if it is an older version, 0.9.65. On the computer I had a problem, I have 0.9.67. I reinstalled Larch completely and now works fine. Thanks for taking the time to work on Larch, Best regards. (^ㅇᆽㅇ^)(=˃ᆺ˂=)(=🝦 ༝ 🝦=) Eugenio H.

Hi Eugenio,

Sorry for the trouble. For sure, interpreting CIF files can be tricky! But, I can read that CIF file with XAS Viewer, larch version 0.9.67. It doesn't fully read all the data about the publication, and it can generate a plausible Feff.inp file. Can you verify that you have a fairly recent version?

I see that there are Unicode characters in the file, but these seem to me to be UTF-8 compatible. If you are still seeing trouble, this might be part of the problem. You might have better luck if you remove these (specifically the line with "_chemical_name_structure_type", which I think you can just remove). If that *does* help, can you also report what your default Unicode encoding is: from either Python or the Larch buffer in XAS Viewer, do

import sys print(sys.getdefaultencoding())

Unfortunately, the current code is not super helpful in reporting why it couldn't read the CIF file - this should be improved!

Hi all, In November I was generating the feff-path in Larch using the .cif file I attached. Now I am generating additional paths from another absorbing atom and I am getting the error message "Error opening .cif file" using the same .cif file. Any ideas? Best regards.
