I'm just about to need to convert some MAF files to fasta alignment files, which from some cursory googling I understand is possible with BioPython/Perl among other tools.
My question is what do the converters actually do to give you the fasta? My understanding at present is that a MAF file contains multiple spans of local sequence alignments, where as an aligned fasta contains sequences that have been gapped until they're the same length.
So when converting, does the resultant fasta simply become all the local alignments concatenated together? Or do you perhaps just get a fasta of every aligned sequence separately?
If it's the latter then I may need a different approach for what I want to do downstream...
