How to set manually training and test data for training a neural network

Hello All,
I am making some experiments with mathlab neural network toolbox. Usually to train a neural network i give some training and test data and the net object takes care of dividing the data. However what i need to do is divide the data by myself and set the training and test data explicitly in the net object.
If it is needed some aditional explanation please tell me. Any help would be appreciated.
Thanks.

From memory, if you look at the help for 'net', it tells you how to do this. You can specify which ranges are used for training, validation and testing. I don't have the neural network toolbox anymore, so I can't be more useful than that.

Read this:
You want the divideind option.

Incidentally, I found that page by googling "matlab neural net data division".
MatLab Answers is great, but often Google is better ;-)

It is probably easier to use 'divideblock'
Hope this helps.
