I keep getting "Error Importing File, Invalid File Format or Could Not Read File" when I try to import a CIF.

The CIF is for Fe. I downloaded it from the Materials Project website, it was the first hit. I attached it by changing the extension to .txt.

What am I missing here?

Thanks for any help!

I would have to look into this particular CIF file. Unfortunately the CIF format is extremely complex and hard to implement perfectly. I don't immediately see the issue with this CIF file. I recommend the American Minerologist repository as a source for CIF files:

Their Fe structure CIF files (and others) are all well formatted and work perfectly.
