[gmx-users] coarse-grained model

[Dongsheng Zhang]

Yang ye,

Thank you very much.

I have three different monomers in my system, so I have 6 different
regular VMDs and 6 different 1-4 interactions. Could you please tell me
how to organize those table.xvg files?

energygrps = gp1 gp2 gp3 gp4 gp5 gp6 ... gp12
energygrp_table = A A B B C C A B A C B C A14 A14 B14 B14 C14 C14 A14
B14 A14 C14 B14 C14 

If I set as the above, I wonder how gromacs know the last 6 table is for
1-4 interaction.

All the best!

Dongsheng
