Bio::SearchIO::hmmer_pull(3) 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').

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
