Java for MSA to compare two sequences from different files

Hi everybody

I have two MSA files 1 and 2. Each file contains 10 sequences from 1 to 10.

I'd like to compare sequence 1 (file 1) with sequence 1 (file 2), sequence 1 (file 1) with sequence 2 (file 2), sequence 1 (file 1) with sequence 3 (file 2)..........., sequence 1 (file 1) with sequence 10 (file 2).

then, the same for sequence 2 (file 1),.................., sequence 10 (file 1).

The same for sequences of the file 2.

Is there any java package that can do that job?

Thanks

sequence

What do you mean by "compare"?

And are these amino acids or nucleotides?

The BBMap package has a program called "idmatrix" that will generate the all-to-all identity values for a single fasta file:

idmatrix.txt in=file.fasta out=matrix.txt

The input has to be a normal fasta file, though, not a msa file with gaps ("-") mixed in with the bases.
