Incorrect topology library used error

Hi,

I was wondering if anyone knows what to do with the following error:

TOP_________> 129 85 CALL ROUTINE = 'create_topology'

TOP_________> 130 100 GENERATE_TOPOLOGY ADD_SEQUENCE = OFF

act54___590E> No topology generated for sequence: prot Possibly because incorrect topology library is used.

It carries out all of the initial alignments without problems, but stops on the 'create_topology' routine.

Any help would be appreciated.

Regards, Seth
