Bio::Seq::LargeSeqI - Interface class for sequences that cache their
residues in a temporary file
No package variables defined.
The interface class defines a group of sequence classes that do not
keep their sequence information in memory but store it in a file. This
makes it possible to work with very large files even with limited RAM.
The most important consequence of file caching for sequences is that
you do not want to inspect the sequence unless absolutely
necessary. These sequences typically override the length() method not
to check the sequence.
The seq() method is not resetable, if you want to add to the end of the
sequence you have to use add_sequence_as_string(), for any other sequence changes you'll
have to create a new object.
Title : add_sequence_as_string
Usage : $seq->add_sequence_as_string("CATGAT");
Function: Appends additional residues to an existing object.
This allows one to build up a large sequence without
storing entire object in memory.
Returns : Current length of sequence
Args : string to append
my ($self) = @_;

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.
