Input selection for ANN

Hi, How can I select the relevant inputs for my neural network model before i built my net? For example: am trying to predict core facies from well logs. i have about 13 well logs and i want to select the relevant well logs that have related to my facies.

Regards, Ghalia

A very quick, non-optimal, but useful method is to use linear models with the help and doc commands on stepwisefit and sequentialfs.
