Thank you for your advice sir. Now I will either put my time and effort to write a Tcl script or try to use MD codes where it has been implemented.

NAMD wasn't implemented with these kind of applications in mind, so it will take some effort on your site. also, if you want to do something that is not commonly done, it is just natural that you cannot expect much specific help. so if you *do* want to use NAMD, you *do* have to invest the time and effort to implement the tools you need.
