#
# March 2007 - first full implementation; needs some file IO tweaking between
# runs but works for now

# July 2009 - updated for v1.0. No longer supporting pre-1.0 Infernal
=head1 NAME
Bio::Tools::Run::Infernal - Wrapper for local execution of cmalign, cmbuild,
cmsearch, cmscore
=head1 SYNOPSIS
# parameters which are switches are set with any value that evals TRUE,
# others are set to a specific value
my $factory = Bio::Tools::Run::Infernal->new(@params);
# run cmalign|cmbuild|cmsearch|cmscore|cmemit directly as a wrapper method
# this resets the program flag if previously set
$factory->cmsearch(@seqs); # searches Bio::PrimarySeqI's based on set cov. model
# saves output to optional outfile_name, returns
# Bio::SearchIO
# only values which are allowed for a program are set, so one can use the same
# wrapper for the following...
$factory->cmalign(@seqs); # aligns Bio::PrimarySeqI's to a set cov. model,
# --merge option allows two alignments generated
# from the same CM to be merged.
# output to outfile_name, returns Bio::AlignIO
$factory->cmscore(); # scores set cov. model against Bio::PrimarySeqI,
# output to outfile_name/STDOUT.
$factory->cmbuild($aln); # builds covariance model based on alignment
# CM to outfile_name or model_file (one is required
# here), output to STDOUT.
$factory->cmemit(); # emits sequence from specified cov. model;
# set one if no file specified. output to
# outfile_name, returns Bio::SeqIO or (if -a is set)
# Bio::AlignIO
$factory->cmcalibrate($file); # calibrates specified cov. model; output to
# STDOUT
$factory->cmstat($file); # summary stats for cov. model; set one if no file
# specified; output to STDOUT
# run based on the setting of the program parameter
my $factory = Bio::Tools::Run::Infernal->new(-program => 'cmsearch',
@params);
my $search = $factory->run($seq);
# using cmsearch returns a Bio::SearchIO object
while (my $result = $searchio->next_result){
while(my $hit = $result->next_hit){
while (my $hsp = $hit->next_hsp){
print join("\t", ( $r->query_name,
$hit->name,
$hsp->hit->start,
$hsp->hit->end,
$hsp->meta,
$hsp->score,
)), "\n";

=head1 DESCRIPTION
Wrapper module for Sean Eddy's Infernal suite of programs. The current
implementation runs cmsearch, cmcalibrate, cmalign, cmemit, cmbuild, cmscore,
and cmstat. cmsearch will return a Bio::SearchIO, cmemit a Bio::SeqIO/AlignIO,
and cmalign a Bio::AlignIO. All others send output to STDOUT. Optionally,
any program's output can be redirected to outfile_name.
We HIGHLY suggest upgrading to Infernal 1.0. In that spirit, this wrapper now
supports parameters for Infernal 1.0 only; for wrapping older versions of
Infernal we suggest using the version of Bio::Tools::Run::Infernal that came
with previous versions of BioPerl-run.
NOTE: Due to conflicts in the way Infernal parameters are now formatted vs.
subroutine naming in Perl (specifically the inclusion of hyphens) and due to the
very large number of parameters available, setting and resetting parameters via
set_parameters() and reset_parameters() is required. All valid parameters can
be set, but only ones valid for the executable set via program()/program_name()
are used for calling the executables, the others are silently ignored.
=head1 FEEDBACK
=head2 Mailing Lists
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.

http://bioperl.org/wiki/Mailing_lists - About the mailing lists
=head2 Support
Please direct usage questions or support issues to the mailing list:
I<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.
=head2 Reporting Bugs
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

Note : Optionally implemented method; up to the implementation on whether
to automatically validate parameters or optionally do so
