Bio::SeqIO::largefasta - method i/o on very large fasta sequence files
Do not use this module directly. Use it via the Bio::SeqIO class.
This object can transform Bio::Seq objects to and from fasta flat
This module handles very large sequence files by using the
Bio::Seq::LargePrimarySeq module to store all the sequence data in
a file. This can be a problem if you have limited disk space on your
computer because this will effectively cause 2 copies of the sequence
file to reside on disk for the life of the
Bio::Seq::LargePrimarySeq object. The default location for this is
specified by the File::Spec->tmpdir routine which is usually /tmp
on UNIX. If a sequence file is larger than the swap space (capacity
of the /tmp dir) this could cause problems for the machine. It is
possible to set the directory where the temporary file is located by
adding the following line to your code BEFORE calling next_seq. See
Bio::Seq::LargePrimarySeq for more information.
$Bio::Seq::LargePrimarySeq::DEFAULT_TEMP_DIR = newdir;
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to one
of the Bioperl mailing lists. Your participation is much appreciated.

Please 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.
Report bugs to the Bioperl bug tracking system to help us keep track
the bugs and their resolution. Bug reports can be submitted via the web:
