mass
should be an attribute of an Element
object, which in this case is None
. This may be due to a strange element in your topology that OpenMM could not recognize. You might workaround that by disabling the status reporters (progress, log), but other problems might arise along the way... so maybe try to fix the topology first.
Hello!
I am trying to run a simulation of a metalloprotein using openmmprotocol, but when the first minimization step starts, it crashes due to the following error:
The protein I am working with has some metals, so I parametrized them before generating the prmtop and inpcrd files. After that, I loaded the parameters in xleap and I generated the .prmtop and .inpcrd files without any errors.
I would like to know where the AttributeError comes from, and how to avoid it in order to run the simulation.
Thank you in advance!
