Dear Dr. Carlos Simmerling,
 
Thanks for your reply! I believe your suggestions is applicable, but you know it is really both time and energy consuming to restrain every clusters one by one. After all there will be thousands of clusters in my system.
 
Furthermore, based on the archives, I find some cases that perform restaint on the protein rather than this cluster solvent. Can you give me more details please?
 
Thanks in advance!

Rilei Yu

you could try using the NMR distance restraints (nmropt=1). there are plenty
of examples in the archives of how to do this.
