Bio::Tools::Run::Cap3(3) User Contributed Perl Documentation Bio::Tools::Run::Cap3(3)

Bio::Tools::Run::Cap3 - wrapper for CAP3

  use Bio::Tools::Run::Cap3;
  # Run Cap3 using an input FASTA file
  my $factory = Bio::Tools::Run::Cap3->new( -clipping_range => 150 );
  my $asm_obj = $factory->run($fasta_file, $qual_file);
  # An assembly object is returned by default
  for my $contig ($assembly->all_contigs) {
    ... do something ...
  # Read some sequences
  use Bio::SeqIO;
  my $sio = Bio::SeqIO->new(-file => $fasta_file, -format => 'fasta');
  my @seqs;
  while (my $seq = $sio->next_seq()) {
    push @seqs,$seq;
  # Run Cap3 using input sequence objects and returning an assembly file
  my $asm_file = 'results.ace';

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.                  - General discussion  - About the mailing lists

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:

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