NAME¶
Bio::SearchIO::hmmer_pull - A parser for HMMER output
SYNOPSIS¶
# do not use this class directly it is available through Bio::SearchIO
use Bio::SearchIO;
my $in = Bio::SearchIO->new(-format => 'hmmer_pull',
-file => 't/data/hmmpfam.bigout');
while (my $result = $in->next_result) {
# this is a Bio::Search::Result::HmmpfamResult object
print $result->query_name(), " for HMM ", $result->hmm_name(), "\n";
while (my $hit = $result->next_hit) {
print $hit->name(), "\n";
while (my $hsp = $hit->next_hsp) {
print "length is ", $hsp->length(), "\n";
}
}
}
DESCRIPTION¶
This object implements a pull-parser for HMMER output. It is fast since it only
does work on request (hence 'pull').

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
list. 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 _
new¶
Title : new
Usage : my $obj = Bio::SearchIO::hmmer_pull->new();
Function: Builds a new Bio::SearchIO::hmmer_pull object
Returns : Bio::SearchIO::hmmer_pull
Args : -fh/-file => HMMER output filename
-format => 'hmmer_pull'
-evalue => float or scientific notation number to be used
as an evalue cutoff for hits
-score => integer or scientific notation number to be used
as a score value cutoff for hits
-hsps => integer minimum number of hsps (domains) a hit must have
-piped_behaviour => 'temp_file'|'memory'|'sequential_read'
-piped_behaviour defines what the parser should do if the input is
an unseekable filehandle (eg. piped input), see
Bio::PullParserI::chunk for details. Default is 'sequential_read'.
next_result¶
Title : next_result
Usage : my $hit = $searchio->next_result;
Function: Returns the next Result from a search
Returns : Bio::Search::Result::ResultI object
Args : none
result_count¶
Title : result_count
Usage : my $count = $searchio->result_count
Function: Returns the number of results we have processed.
Returns : integer
Args : none
rewind¶
Title : rewind
Usage : $searchio->rewind;
Function: Allow one to reset the Result iterator to the beginning, so that
next_result() will subsequently return the first result and so on.
NB: result objects are not cached, so you will get new result objects
each time you rewind. Also, note that result_count() counts the
number of times you have called next_result(), so will not be able
tell you how many results there were in the file if you use rewind().
Returns : n/a
Args : none
