Make matrix of protein pairwise identities/similarities from multiple protein sequences

4

Is there an already existing tool to generate a matrix of pairwise protein identities/similarities for an input which consists of multiple protein sequences?

I did not find a working solution for MAC OS/UNIX (the non-working solution for me is MatGAT for which I managed to find executables only for Windows OS).

I'm aware that parsing results from pairwise alignments of all pairwise combinations of proteins from the input file and arranging it into a table is one solution but I'm trying to avoid this at this point as it would take me, with my current skills, a lot of time to write such a script.

UPDATE
To be more specific, I'm looking for % protein sequence identities from global sequence alignment (such as the % similarities/identities retrieved by www.ebi.ac.uk/Tools/psa/emboss_needle/)


pairwise


protein


identity


similarity


matrix
