The matrix was converted to a symmetric one using A+A', and paritioned using METIS_PartGraphRecursive(). And I got the following error message: ***ASSERTION failed on line 65 of file fm.c: ComputeCut(graph, where) == graph->mincut The matrix A in sparse row format can be found at http://be-research.ucsd.edu/~sylu/cktmatrix_0 Any advice will be greately appreciated!

Check you graph with graphchk to see if it is valid.
