Renamed protein names in final orthogroup table

[nat2bee]

Hi,

When looking at OrthoFinder results I found that for two species the name of the proteins included in each orthogroup does not match the original protein name in the input fasta file, it was renamed to "Species_name_number".
I realized that the two species in question have overlapping protein IDs, i.e., the proteins in the two species have the same names in the fast file. So, I am guessing OrthoFinder renamed the proteins to avoid redundancy. Is that the case?

If so, what is the pattern for protein renaming? Is the "number" in "Species_name_number" referencing the protein position in the fast file? Meaning that the first protein in the file will be "Species_name_1"?

Thanks a lot!
