Bio::Search::Hit::HmmpUseriContributed Perl DocBio::Search::Hit::HmmpfamHit(3)NAMEBio::Search::Hit::HmmpfamHit - A parser and hit object for hmmpfam hits
SYNOPSIS
# generally we use Bio::SearchIO to build these objects
use Bio::SearchIO;
my $in = Bio::SearchIO->new(-format => 'hmmer_pull',
-file => 'result.hmmer');
while (my $result = $in->next_result) {
while (my $hit = $result->next_hit) {
print $hit->name, "\n";
print $hit->score, "\n";
print $hit->significance, "\n";
while (my $hsp = $hit->next_hsp) {
# process HSPI objects
}
}
}
DESCRIPTION
This object implements a parser for hmmpfam hit output, a program in
the HMMER package.

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::Search::Hit::HmmpfamHit->new();
Function: Builds a new Bio::Search::Hit::HmmpfamHit object.
Returns : Bio::Search::Hit::HmmpfamHit
Args : -chunk => [Bio::Root::IO, $start, $end] (required if no -parent)
-parent => Bio::PullParserI object (required if no -chunk)
-hit_data => array ref with [name description score significance
num_hsps rank]
where the array ref provided to -chunk contains an IO object
for a filehandle to something representing the raw data of the
hit, and $start and $end define the tell() position within the
filehandle that the hit data starts and ends (optional; defaults
to start and end of the entire thing described by the filehandle)
next_hsp
Title : next_hsp
Usage : while( $hsp = $obj->next_hsp()) { ... }
Function : Returns the next available High Scoring Pair
Example :
Returns : L<Bio::Search::HSP::HSPI> object or null if finished
Args : none
next_domain
Title : next_domain
Usage : my $domain = $hit->next_domain();
Function: An alias for L<next_hsp()>, this will return the next HSP
Returns : L<Bio::Search::HSP::HSPI> object
Args : none
hsps
Usage : $hit_object->hsps();
Purpose : Get a list containing all HSP objects.
Example : @hsps = $hit_object->hsps();
Returns : list of L<Bio::Search::HSP::BlastHSP> objects.
Argument : none
domains
Title : domains
Usage : my @domains = $hit->domains();
Function: An alias for L<hsps()>, this will return the full list of hsps
Returns : array of L<Bio::Search::HSP::HSPI> objects
Args : none
hsp
Usage : $hit_object->hsp( [string] );
Purpose : Get a single HSPI object for the present HitI object.
Example : $hspObj = $hit_object->hsp; # same as 'best'
: $hspObj = $hit_object->hsp('best');
: $hspObj = $hit_object->hsp('worst');
Returns : Object reference for a L<Bio::Search::HSP::HSPI> object.
Argument : String (or no argument).
: No argument (default) = highest scoring HSP (same as 'best').
: 'best' = highest scoring HSP.
: 'worst' = lowest scoring HSP.
Throws : Exception if an unrecognized argument is used.
See Also : hsps(), num_hsps()
rewind
Title : rewind
Usage : $result->rewind;
Function: Allow one to reset the Hit iterator to the beginning, so that
next_hit() will subsequently return the first hit and so on.
Returns : n/a
Args : none
strand
Usage : $sbjct->strand( [seq_type] );
Purpose : Gets the strand(s) for the query, sbjct, or both sequences.
: For hmmpfam, the answers are always 1 (forward strand).
Example : $qstrand = $sbjct->strand('query');
: $sstrand = $sbjct->strand('hit');
: ($qstrand, $sstrand) = $sbjct->strand();
Returns : scalar context: integer '1'
: array context without args: list of two strings (1, 1)
: Array context can be "induced" by providing an argument of 'list'
: or 'array'.
Argument : In scalar context: seq_type = 'query' or 'hit' or 'sbjct' (default
: = 'query') ('sbjct' is synonymous with 'hit')
frac_aligned_query
Usage : $hit_object->frac_aligned_query();
Purpose : Get the fraction of the query sequence which has been aligned
: across all HSPs (not including intervals between non-overlapping
: HSPs).
Example : $frac_alnq = $hit_object->frac_aligned_query();
Returns : undef (the length of query sequences is unknown in Hmmpfam reports)
Argument : none
