Dear amber users:
  I encountered a strange error when i do the exercise of Case Study: All
Atom Structure Prediction and Folding Simulations of a Stable Protein
(Folding Trp-Cage Peptide).
  In the 6.1.4 section, it says the evaluate expression:
*y = (y < -100) ? y=y+360 : y.* However, my xmgrace prompts:
[Error] syntax error: Y= (Y < -100) ? Y=Y+360 :Y [Error] Error in
do_compute(), check formula

 Can you give me any suggestion? I am not familiar with this.
