faster trajectory writing?
Hello, I'm running some MD where I need to save frames _very_ frequently. Using DCDReporter(), it seems that file writing is the performance bottleneck in my case, which isn't ideal. Do you have any general tips on how I could speed this up? I can't speed up my cluster's file system, but maybe there...

PBC question
If I use PDBFile.writeFile() to save a result of a simulation with PBC, can I use that file as an input for a subsequent simulation with the same PBC? I've been using the context.getState(...).getPositions() method to get coordinates. If I turn on the enforcePeriodicBox option in getState(), the str...

minimizeEnergy() reporter
It would be nice to be able to monitor energy minimization with StateDataReporter(). I haven't been able to make it work. Is there no link between simulation.minimizeEnergy() and simulation.reporters?

Re: AMOEBA FF for NPT, NVT
Thank you! Was worried barostat wasn't supported for AMOEBA. One more q: John Chodera wrote in a old chat "Note that there can be issues when using finite-timestep MD without Metropolization together with a Monte Carlo barostat. The MC samples from the exact Boltzmann distribution, while the MD samp...

Re: Malloc error
I read somewhere that this is a MacOS problem has something to do with permissions, hard to fix (https://stackoverflow.com/questions/223 ... ing-termin).

AMOEBA FF for NPT, NVT
Hi everyone,
I'm very interested in using the AMOEBA FF. I need to equilibrate NPT and NVT before production run. However I saw in OpenMM documentation that "The virial is not calculated for any force." Can you do NPT in OpenMM with AMOEBA?
Thanks!
