Re: [gmx-users] cpu threads in a gpu run

No idea? It seems to be odd. At the beginning of run, I see NOTE: GROMACS was configured without NVML support hence it can not exploit   application clocks of the detected Quadro M2000 GPU to improve performance.   Recompile with the NVML library (compatible with the driver used) or set

Thanks for your help. I completely agree with your points raised. I've dropped the pmx developers and email, hopefully there will be a little bit of wiggle room for me to move forward on this project some time soon. Thanks again, and to Mark and Justin. Anthony Kind regards Anthony Nash PhD

I see your problem. Automating pdb2gmx should be easy if one blindly accepts the protonation states assigned. It does work for most proteins, but I have encountered problematic cases. But, if you notice, weven the pmx web-service seems to use pdb2gmx for generating the topology files. Or else, it r

Hello Abhishek, I think you are onto something there. I've just found the mutres.mtp file. I can understand the idea of simply changing all [X2A] residue topologies but then how do I reflect these changes in the coordinate files? Sorry, this is probably quite simple, I've just stuck between fi

Hello Anthony, Just out of curiosity, I checked the pmx code. It looks like a simple hack into the hybrid residue database (mutres.mtp file, present in the ff directories supplied by the authors) should do the trick. If you look into this file, it contains the full topology and coords for all poss
