Hi everyone,
I have one simple question. I don't know is there any different
between OPLS-AA forcefield and OPLS-AA/L forcefield? I think these
are different but when I use pdb2gmx tool there is no OPLS-AA
forcefield to choose.
There is no difference. The presence of "/L" simply indicates it is
for liquid simulations. I am unaware of a vacuum or gas phase
OPLS-AA, certainly not within Gromacs.

I think that's incorrect. The 'L' in OPLS stands for 'Liquid'. The
trailing /L was added when some parameters were reparameteriezd
(dihedrals I think) at some point, but I don't know what it stands for.
Erik
Thank you
