Thanks but I already checked the literature. What I want to do is, to be
able to trace down the parameters in the nonbonded file like it can be done
for any version of gromos. There are slight changes among different force
fields and I'd like to be able to find that. When I find where it reads
spc/e parameters for c27, i want to play with the parameters that's why i am
asking the file read.
