problem with probabilistic neural network

Hi,
I am working on classifying right and left hand EEG classification. I calculated 6 feature for both left and right hand EEG. Now i want to use probabilistic neural network(PNN) as a classifier. But i dont understand how to do it?

I know how to use back propagation algorithm in matlab but facing problem using PNN as i font understand how give these features as input to network??

It would be so kind if anybody can help.
