Using Bayes Net Toolbox for Matlab

I want to use Bayes Net Toolbox in matlab , especially score_dags(data, ns, dags) function .

I have:

-3 nodes

-All combinational subset of these nodes that create dag (will be 25 dags)

-Array with size (3,30) where each rows represent the data of nodes (e.g. row 1 for node 1), data is 0,1 or -1

- ns_array = [3,3,3]

When I call the function and pass data array as the parameter “data” , and the parameter “dags” is the 25 dags and “ns” parameter is ns_array , the result of the function is always the same, regardless of the data array: -9.76978793044148 -8.42426751081712 -8.42426751081712 7.89691186178541 ,,,,, etc

Why?

I really appreciate any help you can provide.
