why use HMMscan to remove redundant sequences? There are a gazillion deduplication tools out there - just search the forum for FASTA deduplication.

I wrote a perl script to do that. It is called remove_duplicates and you can find it here:

As Ram suggested, there are several tools to do this, one is cd-hit.

Hello guys. I have more than 70,000 protein sequences come from 65 animal species, most of them are TFs. So some of them might be homologous. I like to use CD-HIT to remove the them. But which similarity threshold should I use? Any suggestion?

Here is my free program on Github Sequence database curator (https://github.com/Eslam-Samir-Ragab/Sequence-database-curator)

It is a very fast program and it can deal with:

Nucleotide sequences
Protein sequences

It can work under Operating systems:

Windows
Mac
Linux

It also works for:

Fasta format
Fastq format
