Hi Tom,

It looks from the docs/source like you can, with something like this:

use Bio::SeqIO;
my $seq=Bio::SeqIO->new(-file=>$ARGV[0], -format=>'abi', 
my @atrace=$seq->get_trace_graph(-trace=>'a'); # or c,g,t

Sorry, but I don't have Staden installed so I can't test if this works.
You might also look at the non-BioPerl ABI module on CPAN - again, I 
haven't tested this, but it looks like it could be useful for your purposes:
