Write your own Performance criteria in Neural Network?

Is it possible to write your own stopping criteria in a Neural Network? How should this be done?

I want to use the Mean Squared Error method, but on data not known by the Network.

e.g I use the following divideFcn, so every data will be training data

net.divideFcn = 'dividenull';           %Only training data

(or 'dividetrain' in more recent versions of matlab)

How can I add my personal stopping criteria on an other data set?
