How use your script to trace protein ID based on its tax ID？

[Xueliang24]

Hi, I am a PhD student and use the ncbitax2lin recently. I want to trace the proten ID with NCBI taid, I have download prot.accession2taxid and get the second column and third column (they are gene ID and tax ID), I also downloaded the RefSeq-release215.catalog, because I saw a method the two files can get the lineage information. I also tried use prot.accession2taxid and name.dmp or lineages.csv to get the information according to the FAQ. Maybe it was failed due to the format of these files?

ncbitax2lin currently can only generate lineage info. Not sure about protein IDs.

Or could you tell me how to realize the FAQ？Just like ncbitax2lin ncr_accession2taxid names.dmp.I would like to change the format of these files
