Bio::SearchIO::hmmer_pull - A parser for HMMER output
# 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";
}
}
}
This object implements a pull-parser for HMMER output. It is fast since it only does work on request (hence 'pull').

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
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'.
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
Title : result_count Usage : my $count = $searchio->result_count Function: Returns the number of results we have processed. Returns : integer Args : none
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
