The OpenCL platform, however, allowed as many Context objects as could fit on the device before resources were exhausted. A caveat: I'm still using OpenMM 7. In most cases, it is best to use the pre-built versions OpenMM includes everything one needs to run modern molecular simulations. From the FAQ particle is nan seems to I don't have an openmm development system setup to test and play with this yet--when will a release with this change be cut?

Either I'm misunderstanding how to properly input cutoffs for each of my forces (in which case advice on how to structure my input script is very welcome), or the exception handling in openmm. You can reproduce this yourself by running the HTML-based pdbfixer on 1AO7 to simply build in the hydrogens. openmm.

I think the best we can do with antechamber and GAFF 1/2 without making modifications to ForceField is just to hope that if multiple parameters are generated by parmchk2, they match, so that the undefined behavior of which one will be selected leads to at least the same parameters. app to let users call the converter externally and produce ffxml files from AMBER input files (polymers, carbohydrates, cofactors, or small molecules). 8 was released about 1 year ago, and python 3.

It would be nice if there was an easier way to suppress this logging of a warning as an actual warning using the warnings standard library module. The current situation is that we test the OpenMM Python installation using the command: python-m simtk. I'm not sure what the issue is, although I presume th I'm thinking of merging the simulated tempering and metadynamics scripts into OpenMM.
