The settings in my tutorial are for use with OPLS-AA and are thus not suitable
for a simulation with CHARMM. Cutoffs and other aspects will be different.
You said your goal was energy minimization. The script provided above is for
equilibration after EM. The tutorial also contains an EM script that is more
suitable but will still likely require some small adjustments.
