SYNOPSISDo not use this module directly. Use it via the Bio::AlignIO class.
DESCRIPTIONThis 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.
SupportPlease direct usage questions or support issues to the mailing list:
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Title : write_aln Usage : $stream->write_aln(@aln) Function: writes the $aln object into the stream in fasta format Returns : 1 for success and 0 for error Args : L<Bio::Align::AlignI> object
Title : _get_len Usage : Function: determine number of alphabetic chars Returns : integer Args : sequence string
Title : width Usage : $obj->width($newwidth) $width = $obj->width; Function: Get/set width of alignment Returns : integer value of width Args : on set, new value (a scalar or undef, optional)
