Dear Han,
you can model oligomeric proteins with modeller by separating the different polypeptide chains of the template and the target in the input alignment with the "/" character:
>P1;template structure... AGFWRTYI/AGFWRTYI/AGFWRTYI/AGFWRTYI* >P1;target sequence... -CFYRTYI/-CFYRTYI/-CFYRTYI/-CFYRTYI*
It is pretty straightforward...
Hope this helps,
Oliver
