Dear all,

I posted the similar question several days ago, I got the answer that I can add some information in frcmod or dat file such as the following example.
CJ-CG-CJ-CJ 1 -0.04 0.0 -3 SCEE=1.0 SCNB=1.0
              1 -0.68 0.0 -2 SCEE=1.0 SCNB=1.0
              1 -0.21 0.0 1 SCEE=1.0 SCNB=1.0
But when I set up the parameter, I cannot find difference among the output files, even I set SCEE=10 and SCNB=10. Did I made something wrong? I did not set the SCEE and SCNB in the input files.

Additionally, my water box diffused, I don't know why. I have set up the ntd=1 and added some PBC information in inpcrd file. Does anyone can give me a input file sample for a PBC system?

Sincerely,

Xiaoquan Sun.
