Dear Users,
I am trying to simulate a capped pentapeptide using OPLS force field.
Pdb2gmx runs successfully , however grompp gives following warnings
WARNING 1 [file "topol.top", line 632]:
No default Ryckaert-Bell. types, using zeroes
WARNING 2 [file "topol.top", line 857]:
No default Ryckaert-Bell. types, using zeroes
How should I proceed if these parameters are missing in OPLS.
The topology and gro files are attached herewith
Regards,
Gurpreet
