NAME

Bio::Phylo::Parsers::Fastq - Parser used by Bio::Phylo::IO, no serviceable parts inside

DESCRIPTION

A FASTQ file parser. To use it, you need to pass an argument that specifies the data type of the phred scores into the parse function, i.e.

            

              
              
my $handler_type = _DATUM_;
parse(
   -format => 'fastq',
   -type   => 'illumina', # to indicate how phred scores are scaled
   -file   => 'infile.fastq',
   -flush  => 1, # don't store record, flush and move on
   -handlers => {
    
       # specifies a handler that is executed on each newly created datum
       $handler_type => sub {
           my $seq = shift;
           my @char = $seq->get_char;
           my @anno = @{ $seq->get_annotations };
            
           # print fasta, omit bases with low phred scores
           print ">$seq\n";
           for my $i ( 0 .. $#char ) {
               if ( $anno[$i]->{phred} > 20 ) {
                   print $char[$i];
               }
           }
           print "\n";
       }
   }
);
