GROMACS modification: No
Here post your question :
I’m attempting to generate a topology file using Gromacs with the Drude force field, but I’ve encountered a critical issue. The error message I’m receiving is as follows:
In the .rtp file in residue anisotropic_polarization at line:
DBR6 BR6 C6 C1 C5 1.80000000 0.60000000 0.6000000
Does anyone have a solution for resolving this problem?
You cannot use version 2020.6. None of the GROMACS official releases support Drude. Only the Drude branch of the the git repository has those features. I will warn you that at present it is not production-quality code and should not be used for science you intend to publish.
I appreciate your response greatly.
Are you familiar with any polarizable force fields compatible with GROMACS?
Only trivial shell-type models that are quite old. GROMACS supports some basic features but they aren’t often used.
