I have a protein FASTA sequence file from a specific reference strain. I would like to compare this sequence to the sequences of ~150 other strains of the same species. Does anyone have any suggestions for how to achieve this? I already tried BLAST but it does not seem to pull from many of the strains I am interested in.
I have already downloaded the ~150 proteome files for these strains. So now I just need to figure out how to align a single protein sequence to 150 full proteome files. If there are any easy to use tools like BLAST or MUSCLE that let you essentially create your own database to align to, that would be ideal. That being said, I don't mind learning a bit of R if that would be the best way to approach this problem. Apologies in advance, I'm really a novice when it comes to this but would immensely appreciate any help.
