Bio::AlignIO::fasta - fasta MSA Sequence input/output stream
Do not use this module directly. Use it via the Bio::AlignIO class.
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.
Support Please direct usage questions or support issues to the mailing list: email@example.com 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. Reporting Bugs Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.

Internal methods are usually preceded with a _ next_aln Title : next_aln Usage : $aln = $stream->next_aln Function: returns the next alignment in the stream. Returns : Bio::Align::AlignI object - returns 0 on end of file or on error Args : -width => optional argument to specify the width sequence will be written (60 chars by default) See Bio::Align::AlignI write_aln 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 See Bio::Align::AlignI _get_len Title : _get_len Usage : Function: determine number of alphabetic chars Returns : integer Args : sequence string width 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)
