[Bioperl-l] filtering output from HTMLResultWriter

[Charles Hauser]

Thanks Jason for the tip on passing in functions.
One follow up question. 

I'd like to not write out any $result where either result_filter or
hsp_filter returned 0.

Setting a variable (fail) within the subs has not worked (not visible to
script?).

Suggestions?

C

while( my $result = $in->next_result ) {
    $writer->filter('result'=> \&result_filter );
    while( my $hit = $result->next_hit ) {
	while( my $hsp = $hit->next_hsp ) {
	    $writer->filter('hsp'=> \&hsp_filter );
	    my $out = new Bio::SearchIO(-writer => $writer);
	    $out->write_result($result); <---ONLY IF ALL FILTERS PASSED;
	}
    }
}



sub result_filter {
    my $result = shift;
    return 0 if $result->num_hits =='0';
    return 1;
}



sub hsp_filter {
    my $hsp = shift;
    return 0 if $hsp->length < $MinLen || $hsp->percent_identity <
$MinPID;
    return 1;
}
