Bio::SearchIO::Writer:UseruContribuBio::SearchIO::Writer::ResultTableWriter(3)NAMEBio::SearchIO::Writer::ResultTableWriter - Outputs tab-delimited data
for each Bio::Search::Result::ResultI object.
SYNOPSIS
Example 1: Using the default columns
use Bio::SearchIO;
use Bio::SearchIO::Writer::ResultTableWriter;
my $in = Bio::SearchIO->new();
my $writer = Bio::SearchIO::Writer::ResultTableWriter->new();
my $out = Bio::SearchIO->new( -writer => $writer );
while ( my $result = $in->next_result() ) {
$out->write_result($result, ($in->report_count - 1 ? 0 : 1) );
}
Example 2: Specifying a subset of columns
use Bio::SearchIO;
use Bio::SearchIO::Writer::ResultTableWriter;
my $in = Bio::SearchIO->new();
my $writer = Bio::SearchIO::Writer::ResultTableWriter->new(
-columns => [qw(
query_name
query_length
num_hits
)] );
my $out = Bio::SearchIO->new( -writer => $writer,
-file => ">result.out" );
while ( my $result = $in->next_result() ) {
$out->write_result($result, ($in->report_count - 1 ? 0 : 1) );
}
Custom Labels
You can also specify different column labels if you don't want to use
the defaults. Do this by specifying a "-labels" hash reference
parameter when creating the ResultTableWriter object. The keys of the
hash should be the column number (left-most column = 1) for the
label(s) you want to specify. Here's an example:
my $writer = Bio::SearchIO::Writer::ResultTableWriter->new(
-columns => [qw( query_name
query_length
query_description
num_hits)],
-labels => { 1 => 'QUERY_GI',
2 => 'QUERY_LENGTH' } );
DESCRIPTIONBio::SearchIO::Writer::ResultTableWriter outputs data in tab-delimited
format for each search result, one row per search result. This is a
very coarse-grain level of information since it only includes data
stored in the Bio::Search::Result::ResultI object itself and does not
include any information about hits or HSPs.
You most likely will never use this object but instead will use one of
its subclasses: Bio::SearchIO::Writer::HitTableWriter or
Bio::SearchIO::Writer::HSPTableWriter.
Available Columns
Here are the columns that can be specified in the "-columns" parameter
when creating a ResultTableWriter object. If a "-columns" parameter is
not specified, this list, in this order, will be used as the default.
query_name
query_length
query_description
For more details about these columns, see the documentation for the
corresponding method in Bio::Search::Result::ResultI.

METHODSto_string()
Note: this method is not intended for direct use. The
SearchIO::write_result() method calls it automatically if the writer is
hooked up to a SearchIO object as illustrated in the SYNOPSIS section .
Title : to_string()
:
Usage : print $writer->to_string( $result_obj, [$include_labels] );
:
Argument : $result_obj = A Bio::Search::Result::ResultI object
: $include_labels = boolean, if true column labels are included (default: false)
:
Returns : String containing tab-delimited set of data for each hit
: in a ResultI object. Some data is summed across multiple HSPs.
:
Throws : n/a
column_labels
Usage : print $result_obj->column_labels();
Purpose : Get column labels for to_string().
Returns : String containing column labels. Tab-delimited.
Argument : n/a
Throws : n/a
end_report
Title : end_report
Usage : $self->end_report()
Function: The method to call when ending a report, this is
mostly for cleanup for formats which require you to
have something at the end of the document. Nothing for
a text message.
Returns : string
Args : none
filter
Title : filter
Usage : $writer->filter('hsp', \&hsp_filter);
Function: Filter out either at HSP,Hit,or Result level
Returns : none
Args : string => data type,
