The follwing links provide useful information:
Secondary sturcture prediction type: JPred PHD Other
Please enter the amino acid sequence used to make the prediction (standard 1-letter code)
Please enter the predicted secondary structure (1 letter codes, 'H' is helix, 'E' is strand and '-' or 'C' for coil
Please note, the algorithm will not work unless you supply a predicted secondary sturcture that is the same length as the amino acid sequence.
