Secondary Structure Prediction by Neural Network (ver. 1.1)

Predict locations of alpha-helix and beta-strand from amino acid sequence using Neural Network implemented by Ning Qian and Terrence Sejnowski.

1. Input the amino acid sequence by one of the following ways
   
   
   1. Upload the amino acid sequence file (flat format):
   2. Paste the amino acid sequence in the box:
   
   
   

The method is implemented in this server based on the descrption in the following paper;
Ning Qian and Terrence J. Sejnowski (1988) Predicting the secondary structure of globular proteins using neural network models. J. Mol. Biol. 202, 865-884.
