I should have added
- the nauty package contains the generator “genbg.c” which generates bipartite graphs only, and permits you to specify whether you want isomorphism to preserve colours or otherwise.

I'm trying to enumerate binary (0-1) matrices of a given size that satisfying a specific matrix property (related to finite projection planes), but want to exclude isomorphic matrices, i.e. I don't care about the row or column order of the matrix.
Can nauty help me with this problem? I realize that nauty is designed to work with Graphs rather than Matrices, but thought the same kinds of techniques may be useful.
