NAME

Bio::CUA::SeqIO - a package to parse sequence file if module Bio::SeqIO is unavailable in the system.

SYNOPSIS

        use Bio::CUA::SeqIO;

        # create an IO to a sequence file in FASTA format
        my $io = Bio::CUA::SeqIO->new("seq_file.fa")

        # read each sequence as a Bio::CUA::Seq object from this io
        while(my $seq = $io->next_seq)
        {
                printf("%s: %d\n", $seq->id, $seq->length);
        }
