NAME

Bio::SearchIO::erpin - SearchIO-based ERPIN parser

SYNOPSIS

  # do not call this module directly. Use Bio::SearchIO.

DESCRIPTION

This is an experimental SearchIO-based parser for output from the erpin program. It currently parses erpin output for ERPIN versions 4.2.5 and above; older versions may work but will not be supported.

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::SearchIO::infernal->new();
 Function: Builds a new Bio::SearchIO::infernal object 
 Returns : Bio::SearchIO::infernal
 Args    : -fh/-file     => cmsearch (infernal) filename
           -format       => 'erpin'
           -algorithm    => algorithm (default 'Infernal')
           -query_acc    => query accession, eg. Rfam accession (default undef)
           -hsp_minscore => minimum HSP score cutoff
           -version      => ERPIN version (not reported in output)

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

start_element

 Title   : start_element
 Usage   : $eventgenerator->start_element
 Function: Handles a start element event
 Returns : none
 Args    : hashref with at least 2 keys 'Data' and 'Name'

end_element

 Title   : start_element
 Usage   : $eventgenerator->end_element
 Function: Handles an end element event
 Returns : none
 Args    : hashref with at least 2 keys, 'Data' and 'Name'

element

 Title   : element
 Usage   : $eventhandler->element({'Name' => $name, 'Data' => $str});
 Function: Convenience method that calls start_element, characters, end_element
 Returns : none
 Args    : Hash ref with the keys 'Name' and 'Data'

element_hash

 Title   : element
 Usage   : $eventhandler->element_hash({'Hsp_hit-from' => $start,
                                        'Hsp_hit-to'   => $end,
                                        'Hsp_score'    => $lastscore});
 Function: Convenience method that takes multiple simple data elements and
           maps to appropriate parameters
 Returns : none
 Args    : Hash ref with the mapped key (in %MAPPING) and value

characters

 Title   : characters
 Usage   : $eventgenerator->characters($str)
 Function: Send a character events
 Returns : none
 Args    : string

within_element

 Title   : within_element
 Usage   : if( $eventgenerator->within_element($element) ) {}
 Function: Test if we are within a particular element
           This is different than 'in' because within can be tested
           for a whole block.
 Returns : boolean
 Args    : string element name

in_element

 Title   : in_element
 Usage   : if( $eventgenerator->in_element($element) ) {}
 Function: Test if we are in a particular element
           This is different than 'within' because 'in' only 
           tests its immediate parent.
 Returns : boolean
 Args    : string element name

start_document

 Title   : start_document
 Usage   : $eventgenerator->start_document
 Function: Handle a start document event
 Returns : none
 Args    : none

 Function: Handles an end document event
 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

query_accession

 Title   : query_accession
 Usage   : my $acc = $parser->query_accession();
 Function: Get/Set query (model) accession; Infernal currently does not output
           the accession number (Rfam accession #)
 Returns : String (accession)
 Args    : [optional] String (accession)
