Dear Sir:

In my simulation, I want to fix the bond length of a molecule ( not only the bonds include H atoms) in order to do the vibrational analysis. I know that in charmm I can use
shake to do it. but in NAMD seems like shake can only fix the bonds involve H atoms. is it right? if so, what can I use in NAMD to do this thing. 

Best Regards
