Is there a way to specify a maximum size to Metis or hMetis

Some nodes are very highly connected, while others are much less well connected. hMetis keep breaking apart the small clusters - I'd like to specify a maximum size for the partitions output by hMetis. Is this possible?

RE: hMetis is breaking the

hMetis is breaking the clusters because you are probably asking it to partition the graph into many parts. You can indirectly control the size of the partitions by the number of partitions that you are asking.
