hi,

i have a litle problem with this peace of code:

use Bio::Trace::ABIF;


...

my $abif = Bio::Trace::ABIF->new();

...

foreach my $abifiles (@{$maindata->[1]}){
    $abif->open_abif($abifiles);
    
    print  "$abifiles\n";
    my $sequence = $abif->sequence();

    print  "$sequence\n\n";
        ... and so on 

}

[download]
the problem is that for each argument in my array @{$maindata->1} it prints $abifiles and $sequence variable but when it comes to the last value of the array it just prints variable $abifiles but it doesn't want to return sequences from $abif->sequence() so the $sequence variable stays empty. and only for the last iteration of the foreach loop $sequence is empty. is there a way to solve (flush) this problem or go around it.

it's like he can't open the last $abifiles. i tried to change the order of the arguments in the array and still the last variable is the problem

thanx
