New forcefields implemented in gromacs

[WoutVE]

GROMACS version: 2023
GROMACS modification: No

Hi,

I was wondering if there will be an update with new implemented force fields, such amber19sb, bsc1 and the watermodel opc. Because if I understand it correctly, DNA is parametrized using AMBER94 when using the AMBER99SB force field.

As of now I am using the CHARMMGUI website, but it tends to be slow when doing over 40+ different complexes and I can’t really get the hang of AmberTools22 due to the complexity (DNA,protein and zinc ions complex) and limited information on it.

Warm regards,
Wout, master student at KU Leuven
