mtmetis_nd()

I am trying to switch from METIS_NodeND() to mtmetis_nd() but i keep getting the "Incorrect sum of 0.000000 for tpwgts for constraint 0" error.
I run mtmetis_nd( n, xadj, adj, NULL, NULL, perm ) instead of METIS_NodeND( &n, xadj, adj, NULL, NULL perm, iperm )
xadj & adj arrays are csr 0-based, am i doing something wrong? maybe wait until an "options" array is passed in mtmetis_nd()?
I use mtmetis 0.4.4 on Linux with GCC 4.4.6
Thanks!

RE: Your call looks correct. Can

Your call looks correct. Can you email me the graph/csr that you're passing in? (lasalle at cs.umn.edu).

Thanks,

Dominique
