We are using OBO Edit () to manage vertebrate trait ontology development. When we port the OBO files from OBO Edit to Amigo for display, a small portion of the entries give rise to complains like:
DBD::mysql::st execute failed: Duplicate entry '283-7-1' for key 1 at /usr/lib/perl5/site_perl/5.8.8
/DBIx/DBStag.pm line 3314.
I wonder if it is a real "duplicate key" problem, as I thought the "keys" within OBO Edit must be managed to be unique? Does similar problem happen to others? Thank you.
