[gmx-users] question about GBSA and opls-aa

[Baoqiang Cao]

Hi,

I'm using GBSA with opls-aa force field and have some questions that I
couldn't find answers, I'd definitely be grateful if could get answer
of tips. How does GBSA treat 1-2(covalent bonded), 1-3(bonded angle),
1-4(improper torsion) interactions? Should they all contribute nothing
to GBSA energy or except 1-4?  Thanks in advance!
