Hi ,
     I am new to NAMD. I have gone through the NAMD tutorial just now.

I have a doubt regarding restraining atoms. Suppose I have a .pdb file and
its contains 1000 residues. Now I want to restrain the only backbone
atoms(CA,N,C) from residue 1 to residue 800, and others will be free. What
should I do in this case ? Can you please explain it in detail.

Thanks in advance.
