hi. i want to ask, if i want to select protein from a blastp result , which parameter should i look closely before i select a protein. evalue, percent identity or score? and if there is E-Value = 0, is it okay to choose that e-value or i have to take a look at the e-value that is near 0?

thank you.

I'm not sure what the question is exactly, but it sounds like you're asking what the best result is?

Your best match from BLAST will have an E-Value as close to 0 as possible (0 is as good as it gets), and ideally will have a large Bitscore. You may need to look at the query coverage etc however if you're just interested in a particular sub-region of the protein etc.
