[Bioperl-l] SwissProt SQ Line

[Jonathan B Joseph]

I have been able to obtain all the swissprot information I need with the 
exception of the information on the SQ Line via bioperl api calls.  Is there 
a way to obtain the information on the SQ line via bioperl API calls on a 
bioperl object (such as the Bio::Annotation::Collection object)?  I am 
particularly interested in the molecular weight and crc64.  Currently, I am 
using bioperl calls to compute the molecular weight and crc64, but would like 
to have the option of just extracting this information from the SQ line.

I am looping throught Bio::Seq objects via the following code:

my $stream = Bio::SeqIO->new( -format => 'swiss', -file => $filepath);
 while ( my $seq = $stream->next_seq() ) {
# bioper api calls
}

Within each loop I make API calls to obtain information from the sequence 
record.   I believe that the version of bioperl that I'm using is at least 
version1.0, but don't know how to find out. ($VERSION in Seq.pm is set to 
1.0).

Thanks for your help,
Jonathan
