@howardisaacson I'm getting the following error in the CI tests:

I think that the old version of the file might not have had a header row?

[howardisaacson]

The old version also has a header row. Both have an index column, which can be removed if needed. There are no letters (such as NaN) in the new file. Not clear what the problem is.

I went ahead and fixed it.
