I've never really needed to convert to GTF, but at one point bioperl
supported gtf as gff 2.5
http://doc.bioperl.org/releases/bioperl-1.5.1/Bio/FeatureIO/gff.html
So once blat data are in gff3, a conversion from gff3 to gtf would work like
my $inGFF = Bio::FeatureIO->new( '-file' => "$inFile",
'-format' => 'GFF',
'-version' => 3 );my $outGTF = Bio::FeatureIO->new( '-file' => ">$outFile",
'-format' => 'GFF',
'-version' => 2.5);
while (my $feature = $inGFF->next_feature() ) {
$outGTF->write_feature($feature);
}
