[Bioperl-l] pir format for input and output os sequences

[luisa pugliese]

Hi Bioperlers,
    I am interessed at working with the pir format because it is widely used
in homology modeling.
I saw that among bioperl SeqIO methods there is also pir and that the print
section of this method is:

return unless $self->_print(">P1;".$seq->id(),
        "\n", $seq->desc(), "\n",
        $str, "*\n");

In the second line the method would write:

$seq->desc().

I would like to fill this line with proper informations, but I didn't find
the description of the desc method .
Does anybody knows where can I find it or how can I pass some informations
to it?
Best regards
Luisa
