Hello, I'd like to report an error I encounter when using the RPMDIntegrator in the latest version of OpenMM. When I call getState() on the RPMDIntegrator I receive the following error:

Code: Select all

Traceback (most recent call last):
  File "run-dynamics.py", line 135, in <module>
    state = simulation.integrator.getState(0, getPositions=True)
  File "/cstor/stanford/tem26/users/jnapoli/anaconda/lib/python2.7/site-packages/simtk/openmm/openmm.py", line 3652, in getState
    self._getStateAsLists(getP, getV, getF, getE, getPa, getPd, enforcePeriodic, groups_mask)
TypeError: _getStateAsLists() takes exactly 10 arguments (9 given)

_getStateAsLists() seems to be missing an argument. Am I calling getState() incorrectly in the example above?

Thank you!

Joe

Which version of OpenMM is this with? 7.1.1, or the latest development code from github?

Hi Peter,

It is with version 7.1.1 installed via conda:

Code: Select all

# packages in environment at /cstor/stanford/tem26/users/jnapoli/anaconda:
#
openmm                    7.1.1                    py27_0    omnia

I'm not sure what's going on with that, but could you try the latest development code? I'm pretty sure the error won't happen there, because _getStateAsLists() doesn't exist anywhere. We've rewritten the whole way states get represented in Python. So this should be fixed in the next release.
