NAME
Bio::AlignIO::fasta - fasta MSA Sequence input/output stream
SYNOPSIS
Do not use this module directly. Use it via the Bio::AlignIO class.
DESCRIPTION
This object can transform Bio::SimpleAlign objects to and from fasta flat files. This is for the fasta alignment format, not for the FastA sequence analysis program. To process the alignments from FastA (FastX, FastN, FastP, tFastA, etc) use the Bio::SearchIO module.
FEEDBACK
Support
