NAME

Bio::SearchIO::Writer::HTMLResultWriter - write a Bio::Search::ResultI in HTML

CONTENTS

SYNOPSIS



  use Bio::SearchIO;
  use Bio::SearchIO::Writer::HTMLResultWriter;

  my $in = Bio::SearchIO->new(-format => blast,
                             -file   => shift @ARGV);

  my $writer = Bio::SearchIO::Writer::HTMLResultWriter->new();
  my $out = Bio::SearchIO->new(-writer => $writer);
  $out->write_result($in->next_result);


  # to filter your output
  my $MinLength = 100; # need a variable with scope outside the method
  sub hsp_filter {
      my $hsp = shift;
      return 1 if $hsp->length(total) > $MinLength;
  }
  sub result_filter {
      my $result = shift;
      return $hsp->num_hits > 0;
  }

  my $writer = Bio::SearchIO::Writer::HTMLResultWriter->new
                     (-filters => { HSP => \&hsp_filter} );
  my $out = Bio::SearchIO->new(-writer => $writer);
  $out->write_result($in->next_result);

  # can also set the filter via the writer object
  $writer->filter(RESULT, \&result_filter);



DESCRIPTION

This object implements the SearchWriterI interface which will produce a set of HTML for a specific Bio::Search::Report::ReportI interface.

See Bio::SearchIO::SearchWriterI for more info on the filter method.

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.

           : and HSPTableWriter.pm.
 Usage     : print $writer->to_string( $result_obj, @args );

           link(s) for the given hit to be used
           within the description section at the top of the BLAST report.
           This allows a person reading the report within
           a web browser to go to one or more database entries for
           the given hit from the description section.

           a web browser to go to one or more database entries for
           the given hit from the description section.
 Returns : string containing HTML markup "<a href...")

           The default implementation returns an HTML link to the
           URL supplied by the remote_database_url() method
           and using the identifier supplied by the id_parser() method.
           It will use the NCBI GI if present, and the accession if not.

           This allows a person reading the report within
           a web browser to go to one or more database entries for
           the given hit from the alignment section.
 Returns : string containing HTML markup "<a href...")

           The default implementation delegates to hit_link_desc().

 Function: Parses the description line information, splits based on the
           hidden \x01 between independent descriptions, checks the lines for
