Bio::SearchIO::erpin(3)

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.

FEEDBACK

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

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

  end_document
 Title   : end_document
 Usage   : $eventgenerator->end_document
 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)

  hsp_minscore
 Title   : hsp_minscore
 Usage   : my $cutoff = $parser->hsp_minscore();
