NAME ^

Bio::AlignIO::largemultifasta - Largemultifasta 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 largemultifasta flat file databases. This is for the fasta sequence format NOT FastA analysis program. To process the pairwise alignments from a FastA (FastX, FastN, FastP, tFastA, etc) use the Bio::SearchIO module.

Reimplementation of Bio::AlignIO::fasta modules so that creates temporary files instead of keeping the whole sequences in memory.

FEEDBACK ^

Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

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.

APPENDIX ^

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

next_seq

 Title   : next_seq
 Usage   : $seq = $stream->next_seq()
 Function: returns the next sequence in the stream while taking care
           of the length
 Returns : Bio::Seq object
 Args    : NONE

next_aln

 Title   : next_aln
 Usage   : $aln = $stream->next_aln()
 Function: returns the next alignment in the stream.
 Returns : L<Bio::Align::AlignI> object - returns 0 on end of file
        or on error
 Args    : NONE

write_aln

 Title   : write_aln
 Usage   : $stream->write_aln(@aln)
 Function: writes the $aln object into the stream in largemultifasta format
 Returns : 1 for success and 0 for error
 Args    : L<Bio::Align::AlignI> object
