Neural Network Problem

[DrNick]

Hi, I have a bit of a niche question here and you'll have to forgive any ignorance as i know very little about the subject matter.

I want to write a protein secondary structure prediction from sequence program that uses a neural network(s). Problem is I don't know much about neural networks and neither do any of the lecturers on my course. I have a AI text book by Janet Finlay but it's very vague about it.

I was wondering if anyone has studied ANNs and could reccommend any material which would allow me to learn how to write a backpropagation neural network. I need something for someone who doesn't know much at all about ANNs.
