[Bioperl-l] question about Bio::DB::GFF

[xianran li]

  Hi,
   
  I tried to load the  gff3 file with load_gff.pl and extrac some information with Bio::DB::GFF. Althougth this code work properly under windows xp, the $seg got nothing when i run it under Linux. 
   
  Here is my code and the gff3 file,
  ####################################################################
   
    #!/usr/local/bin/perl -w
   
  use strict;
use Bio::SeqIO;
use Bio::DB::GFF; 
   
  my $in_gff = Bio::DB::GFF->new( -adaptor    => 'dbi::mysqlopt',
                                -dsn        => 'dbi:mysql:test',
                                -aggregator => ['coding'],
                                -user       => "lixr",
                                -pass       => "123456"
                                );                           
my $seg = $in_gff->segment'BGIOSIBCE000001.1');
print $seg->abs_start."\n";
