Hi all,
I would like to investigate how point mutations in one protein affect the
binding affinity of protein-protein interaction using Amber18. Running
Amber-TI module as-is results in an error saying that the maximum number of
softcore atoms is 200. Looking through the mailing list, I saw that I could
change that limit by modifying the file: "cuda/gti_simulationConst.h" so
that I have a higher limit:
MaxNumberTIAtom = 4000
MaxNumberTIPair = 2000
GPUPotEnergyTerms = 800
GPUKinEnergyTerms = 200
However, this results in a different error:
Error in `pmemd.cuda_DPFP': double free or corruption.
Is this coming from a lack of available memory? I was just wondering
whether it is possible to do Amber-TI on P-P interactions through
modifications of the existing code?
Thanks!
Wanlei
