FieldMetaType error in Swarming

Any ideas about where this error is coming from? I’ve tried a few things but can’t seem to solve it.

Exception: Invalid file format for "/home/myswarm/data/Alpha_interictal.csv" - field type "" not a valid FieldMetaType

I’d try changing those second lines from <type ‘float’> to just: float

Yeah, I’ve tried this, no luck

You have an empty field (the first column). Give it a name and a type (like count and int) even if you’re not processing it.

Slightly delayed repose, but thanks rhyolight, I found you can add this when saving a CSV to remove the index when saving

df.to_csv(path, index=False)
