| Adding sequences to an existing MSA |
|
To add a sequence to an existing alignment that you wish to keep intact, use profile-profile alignment with the new sequence as a profile. Examples muscle -profile -in1 existing_msa.afa -in2 new_seq.fa -out combined.afa If you have more than one, you can align them first then add them, for example: muscle -in new_seqs.fa -out new_seqs.afa muscle -profile -in1
existing_aln.afa -in2 new_seqs.afa -out combined.afas |
