Dear Users
I have a system in of protein with in bound chlorine ion. I also added Na ion to the system to neutralize charge on system. I have to couple the system to water bath. can i couple protein chlorine and Na together and solvent separately? or should i couple protein and chlorine together and solvent and na together?

Don't use T-coupling groups that might have molecules isolated inside regions filled by other T-coupling groups. That won't be numerically stable.

I the later case -n option would take in 2 index files. then what should I do?

You can make both groups inside the one index file.
