@hanboy315 I edited your post to make it more clear.

Thank you for the bug report! Can you share the script you used that produced this error? What is the output of conda list for your environment?

@hanboy315 The error is because you are trying to create a Simulation object from the topology and the system but the system only has the small molecule (from the mol file), whereas the topology is presumably the receptor (from the pdb file). Therefore these two are incompatible (they are not referring to the same systems). For a way to create an unified topology and system with both the receptor and the molecule you can check this example from the openff tutorials.

Hello! Many thanks for the reply. I'm trying to build a box of small molecules only. So I've allowed the topology to be the same as my 'molecule'. If there is only one molecule it works (sure) but if it's >1 the problem remains. My .py now looks something like this. My workflow begins with packmol'ing two small molecules and that is the Y6_2_out.mol/.gro

and the error remained to be

openmm.OpenMMException: Called setPositions() on a Context with the wrong number of positions

This is a good question, but looks like it belongs in the espaloma repository and not perses since it doesn't look like your script uses perses?

I'll re-open this and transfer it since it has more info (more like the context of our conversation) then the new one you opened @hanboy315

@ijpulidos @yuanqing-wang any ideas here?

We worked around this by borrowing approaches in #192 and using the EspalomaTemplateGeneratorwhich we then put in an openff.Forcefield object in order to use the openmm.app.Modeller. This approach seemed to be happily start a multi-molecule input file in Espaloma, and though I have not checked carefully the Forcefield is correct, the dynamics looked sensible.
I'm always a bit lost debugging Python and end up trying different instantiated objects until something works.

@ijpulidos we should update our docs to include a little example like this
