retrival from arb format

Question

[nittaym]

Hi! I'm working on nifH (nitrogenase) sequences. I've looked a lot for the best DB for nifH and came up with a DB that seems comprehensive (https://www.jzehrlab.com/nifh ). Problem is, it's in arb format! I tried to export the DB to other formats, the problem is that I can only retrieve the sequences with no species info, only an ID which doesn't correspond to any known GeneID. Someone has experience with this old-school program and could maybe help me with how to retrieve the info?
