I'm looking for sequence alignment software used in pairwise sequence alignment , which can be used for ungapped local protein alignment with custom substitution matrix.
I found out that in NCBI blastp there is -ungapped parameter but when it comes to -matrix parameter only BLOSUM80, BLOSUM62, BLOSUM50, BLOSUM45, PAM250, BLOSUM90, PAM30, PAM70 and IDENTITY are supported and it is not possible to use custom matrices stored in text file.
I would be grateful for pointing out similar software with such a functionality.
