structure learning problem

[snowave]

hi, I have read my dataset into the ds object, i'm running structure learning below:
cout << "\nstructure learning1..." << endl;
DSL_greedyThickThinning gtt;
DSL_network net2;

if (gtt.Learn(ds, net2) != DSL_OKAY) {

cout << "Cannot learn structure... exiting." << endl;
exit(7);
}

net2.WriteFile("store_struct_gtt.xdsl", DSL_XDSL_FORMAT);

The problem is there is no error showing but gtt.Learn does not work. Using GeNie interface for my dataset is fine. The dataset contains 44 variables and 3000 records.

Thanks
Snowave

Do you mean your network has no nodes?
