GROMACS version: 2026.0=nompi_cuda_h39c90b0_0
GROMACS modification: No

Dear community,

I would like to use the LignAmb25 force field in pdb2gmx.

Unfortunately, unlike CHARMM36, you can’t simply download the LignAmb25 force field and use it directly with the -ff option.

Although this page describes how to access AMBER force fields, it doesn’t include any forcefield.itp files, and the directory structure is completely different.

So far, I haven’t found a way to export the LignAmb25 force field so that it can be used with pdb2gmx -ff.

Hence my question: when will the LignAmb25 force field be officially included in GROMACS?
