Nick,

> Can't call method "seq" on an undefined value at Match-emNEWTEST.pl line 84,

The error makes it pretty clear. You are calling the ->seq method on
an undefined value, ie. $pse_obj.

> my $pse_obj = $db->get_Seq_by_id('GA17307');

# check we got something!
die "sequence not in database" unless $pse_obj;

> my $pse_sequence = $pse_obj->seq;
