"ValueError: could not convert string to float" in convert_eggnog_to_homologs()

[Zaffe24]

Dear @atarashansky,

I encountered an error when running the convert_eggnog_to_homologs() function.
I would be very glad if you could help me solve this issue.
Best regards,
Pietro

I am using numpy 1.21.6 on Python3.7, I believe it entered in conflict with line 1109.

Here is a snapshot of one of the EGGNOG tables I am using:

Hey there @Zaffe24,

I was just playing around with eggNOG outputs and the 'convert_eggnog_to_homologs' function, and I ran into the same issue. It turns out that I had duplicate values in my 'query' column from the eggNOG table.

I'd first make sure that the data in the 'query' column are identical to the genes in your SAMap object (prior to the species annotation , e.g. 'mm_'), and then I would check for duplicates in that column!

I hope that helps, and good luck!
