Yes that should work, if it doesn't please let me know!
from openfe.
We support custom force fields if they comply with the smirnoff spec so anything that openff makes or you create with bespoke fit should work.

I have also been trying to use espaloma as the small molecule force field. #682
It seems it should be possible to use espaloma #229
Can you please give a minimal example of using espaloma?
Thanks.
from openfe.
Ah! Okay yes this is supported, I don't have time right now to test this, but it should be as easy as specifying espaloma-0.3.2
as the forcefeield you want to use, is that what you mean?
OH! I see in #682 it looks like openmmforcefeild needs an update to support espaloma-0.3.2
since it only supports espaloma-0.2.2
currently. Tracking that issue here openmm/openmmforcefields#336
from openfe.
Thanks! @mikemhenry, on this topic, is it possible to change it inside yaml file like this?
protocol:
settings:
forcefield_settings:
small_molecule_forcefield: 'espaloma-0.2.2'
protocol_repeats: 2
from openfe.
Hey @mikemhenry, thanks for checking, I just tried but in the output json file I still have the default, openff-2.1.1
for small_molecule_forcefield
and 3 for protocol_repeats
, my settings.yaml
file looks like this:
mapper:
method: lomap
# method: kartograf
network:
method: generate_radial_network
settings:
central_ligand: 'lig_ejm_31'
# method: generate_radial_network
# method: generate_maximal_network
# method: generate_minimal_redundant_network
protocol:
settings:
forcefield_settings:
small_molecule_forcefield: 'espaloma-0.2.2'
protocol_repeats: 2
The command I run is openfe plan-rbfe-network -M tyk2_ligands.sdf -p tyk2_protein.pdb -o network_setup -s settings.yaml
from openfe.
@wenchangzhou-qtx, CLI YAML inputs for Protocols is not currently available in the 1.0 release of openfe. It should make it soon but for now if you want non-default settings you'll have to use the Python API.
