There are two parameters for controlling EM algorithm:
1) 'confidence level'. It's described in the dialog box shown after matching network and data and before running EM; see this thread for more information:

2) 'randomize initial parameters' - this one should be self-explanatory. Note that when randomization is on, you can't specify the confidence level.
I believe in your case you should just use the default EM parameters, since your network has fixed structure and you're learning params from scratch.
