Bio::Search::Hit::HMMERHit - A Hit module for HMMER hits
use Bio::Search::Hit::HMMERHit;
my $hit = Bio::Search::Hit::HMMERHit->new();
# use it in the same way as Bio::Search::Hit::GenericHit
This is a specialization of Bio::Search::Hit::GenericHit. There are a few news methods next_domain and domains. Note that bits and iteration make no sense for this object and will return 0.
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.

Please direct usage questions or support issues to the mailing list:

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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new
Usage : my $obj = Bio::Search::Hit::HMMERHit->new();
Function: Builds a new Bio::Search::Hit::HMMERHit object
Returns : Bio::Search::Hit::HMMERHit
Args :
Plus the Bio::Search::Hit::GenericHit inherited params
-name => Name of Hit (required)
-description => Description (optional)
-accession => Accession number (optional)
-length => Length of the Hit (optional)
-score => Raw Score for the Hit (optional)
-significance => Significance value for the Hit (optional)
-algorithm => Algorithm used (BLASTP, FASTX, etc...)
-hsps => Array ref of HSPs for this Hit.
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
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
Title : add_hsp Usage : $hit->add_hsp($hsp) Function: Add a HSP to the collection of HSPs for a Hit Returns : number of HSPs in the Hit Args : Bio::Search::HSP::HSPI object
Title : name Usage : $hit_name = $hit->name(); Function: returns the name of the Hit sequence Returns : a scalar string Args : [optional] scalar string to set the name
Title : accession Usage : $acc = $hit->accession(); Function: Retrieve the accession (if available) for the hit Returns : a scalar string (empty string if not set) Args : none
Title : description Usage : $desc = $hit->description(); Function: Retrieve the description for the hit Returns : a scalar string Args : [optional] scalar string to set the description
Title : length Usage : my $len = $hit->length Function: Returns the length of the hit Returns : integer Args : [optional] integer to set the length
Title : algorithm
Usage : $alg = $hit->algorithm();
Function: Gets the algorithm specification that was used to obtain the hit
For BLAST, the algorithm denotes what type of sequence was aligned
against what (BLASTN: dna-dna, BLASTP prt-prt, BLASTX translated
dna-prt, TBLASTN prt-translated dna, TBLASTX translated
dna-translated dna).
Returns : a scalar string
Args : [optional] scalar string to set the algorithm
Title : raw_score
Usage : $score = $hit->raw_score();
Function: Gets the "raw score" generated by the algorithm. What
this score is exactly will vary from algorithm to algorithm,
returning undef if unavailable.
Returns : a scalar value
Args : [optional] scalar value to set the raw score
Title : significance
Usage : $significance = $hit->significance();
Function: Used to obtain the E or P value of a hit, i.e. the probability that
this particular hit was obtained purely by random chance. If
information is not available (nor calculatable from other
information sources), return undef.
Returns : a scalar value or undef if unavailable
Args : [optional] scalar value to set the significance
Usage : $hit_object->bits(); Purpose : Gets the bit score of the best HSP for the current hit. Example : $bits = $hit_object->bits(); Returns : Integer or undef if bit score is not set Argument : n/a
See Also : score()
Title : next_hsp
Usage : while( $hsp = $obj->next_hsp()) { ... }
Function : Returns the next available High Scoring Pair
Example :
Returns : Bio::Search::HSP::HSPI object or null if finished
Args : none
Usage : $hit_object->hsps();
Purpose : Get a list containing all HSP objects.
: Get the numbers of HSPs for the current hit.
Example : @hsps = $hit_object->hsps();
: $num = $hit_object->hsps(); # alternatively, use num_hsps()
Returns : Array context : list of Bio::Search::HSP::BlastHSP.pm objects.
: Scalar context: integer (number of HSPs).
: (Equivalent to num_hsps()).
Argument : n/a. Relies on wantarray
Throws : Exception if the HSPs have not been collected.
See Also : hsp(), num_hsps()
Usage : $hit_object->num_hsps(); Purpose : Get the number of HSPs for the present Blast hit. Example : $nhsps = $hit_object->num_hsps(); Returns : Integer Argument : n/a Throws : Exception if the HSPs have not been collected.
See Also : hsps()
Title : rewind
Usage : $hit->rewind;
Function: Allow one to reset the HSP iteration to the beginning
Since this is an in-memory implementation
Returns : none
Args : none
Title : iteration Usage : $obj->iteration($newval) Function: PSI-BLAST iteration Returns : value of iteration Args : newvalue (optional)
