NAME ^

Bio::SearchIO::SearchResultEventBuilder - Event Handler for SearchIO events.

SYNOPSIS ^

# Do not use this object directly, this object is part of the SearchIO # event based parsing system.

DESCRIPTION ^

This object handles Search Events generated by the SearchIO classes and build appropriate Bio::Search::* objects from them.

FEEDBACK ^

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.

 Args    : name of factory class to retrieve

See Bio::Factory::ObjectFactoryI for more information

inclusion_threshold

See Bio::SearchIO::blast::inclusion_threshold.

max_significance

 Usage     : $obj->max_significance();
 Purpose   : Set/Get the P or Expect value used as significance screening cutoff.
             This is the value of the -signif parameter supplied to new().
             Hits with P or E-value at HIT level above this are skipped.
 Returns   : Scientific notation number with this format: 1.0e-05.
 Argument  : Number (sci notation, float, integer) (when setting)
 Throws    : Bio::Root::BadParameter exception if the supplied argument is
           : not a valid number.
 Comments  : Screening of significant hits uses the data provided on the
           : description line. For NCBI BLAST1 and WU-BLAST, this data
           : is P-value. for NCBI BLAST2 it is an Expect value.

signif

Synonym for max_significance()

min_score

 Usage     : $obj->min_score();
 Purpose   : Gets the Blast score used as screening cutoff.
             This is the value of the -score parameter supplied to new().
             Hits with scores at HIT level below this are skipped.
 Returns   : Integer (or undef if not set)
 Argument  : Integer (when setting)
 Throws    : Bio::Root::BadParameter exception if the supplied argument is
           : not a valid number.
 Comments  : Screening of significant hits uses the data provided on the
           : description line.

min_bits

 Usage     : $obj->min_bits();
 Purpose   : Gets the Blast bit score used as screening cutoff.
             This is the value of the -bits parameter supplied to new().
             Hits with bits score at HIT level below this are skipped.
 Returns   : Integer (or undef if not set)
 Argument  : Integer (when setting)
 Throws    : Bio::Root::BadParameter exception if the supplied argument is
           : not a valid number.
 Comments  : Screening of significant hits uses the data provided on the
           : description line.

hit_filter

 Usage     : $obj->hit_filter();
 Purpose   : Set/Get a function reference used for filtering out hits.
             This is the value of the -hit_filter parameter supplied to new().
             Hits that fail to pass the filter at HIT level are skipped.
 Returns   : Function ref (or undef if not set)
 Argument  : Function ref (when setting)
 Throws    : Bio::Root::BadParameter exception if the supplied argument is
           : not a function reference.
