NAME
Bio::Assembly::Scaffold - Perl module to hold and manipulate sequence assembly data.
SYNOPSIS # # Module loading use Bio::Assembly::IO;
# Assembly loading methods
my $aio = Bio::Assembly::IO->new(-file=>"test.ace.1", -format=>'phrap');
my $assembly = $aio->next_assembly;
foreach my $contig ($assembly->all_contigs) {
# do something... (see Bio::Assembly::Contig)
}
DESCRIPTION
Bio::Assembly::Scaffold was developed to store and manipulate data from sequence assembly
programs like Phrap. It implements the ScaffoldI interface and intends to be generic
enough to be used by Bio::Assembly::IO drivers written to programs other than Phrap.
FEEDBACK
Mailing Lists
User feedback is an integral part of the evolution of this and other Bioperl modules. Send
your comments and suggestions preferably to the Bioperl mailing lists Your participation
is much appreciated.

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 _

(sequences from contigs and singlets, not consensus).
Returns : array of strings
Args : none
get_nof_seqs
Title : get_nof_seqs

Title : get_contig_seq_ids
Usage : $assembly->get_contig_seq_ids()
Function: Get the ID of all sequences in contigs
Returns : array of strings
Args : none
get_contig_ids
Title : get_contig_ids
Usage : $assembly->get_contig_ids()

assembly. An empty array otherwise

Title : get_singlet_ids
Usage : $assembly->get_singlet_ids()

Modifier methods
add_contig
Title : add_contig
Usage : $assembly->add_contig($contig)

order (optional)

order (optional)

Title : update_seq_list
Usage : $assembly->update_seq_list()

Title : remove_features_collection
Usage : $assembly->remove_features_collection()
Function: Removes the collection of features associated to every
contig and singlet of the scaffold. This can be useful
to save some memory (when contig and singlet features are
not needed).
Returns : none
Argument : none
Contig and singlet selection methods

all_contigs
Title : all_contigs
Usage : my @contigs = $assembly->all_contigs
Function:
Returns a list of all contigs in this assembly. Contigs
are both clusters and alignments of one or more reads,
with an associated consensus sequence.
Returns : array of Bio::Assembly::Contig (in lexical id order)
