Greetings

Hello all,

I have a two set of protein sequence from two different sources for e.g., from phytozome and refseq, how I can match between these so I can find how many are common between them.

If you want to find sequences from one set that are most similar to sequences from the other set then align sequences from one set against all sequences from the other and set a threshold on the similarity score or simply take the best match depending on what you're trying to achieve.
