Dear Mark Abraham,
Thank you for the reply. However, I am sorry to tell you that I could
not find a tutorial that really is explicit to explain the procedure.
Could you please suggest some tutorial covering the non-water solvent
box generation and optimization using all-atom charmm force-field on
GROMACS.
Please do not include the whole digest in your replies. Cut and paste any
relevant text and delete the rest. Including the whole digest makes the archive
terribly confusing.
To the point: there aren't going to be tutorials that cover every possible
iteration of what someone wants to do. Generate a reasonable starting
configuration and equilibrate under an appropriate ensemble. If you want
explicit pointers on what may or may not be right or wrong with your .mdp
settings, you need to post an .mdp file for comment. Achieving a periodic
system under NVT conditions is simple (and discussed in just about every
tutorial, even if the goal of the tutorial is not explicitly what you want to
do). Set "pbc = xyz" and use the thermostat of your choice with no pressure
coupling. Presto - NVT ensemble.
