Dear all,
I have a simple question that I hope somebody could clarify for me. It's
about the Gnp settings in MM/PBSA.
&pb and &gb has different namelist variables. I am using inp=1 option which
calculates Gnp linearly to SASA (gamma*SASA+b). There are different sets of
gamma and b.
In &pb namelist, I used cavity_surften (gamma) and cavity_offset (b) to
change the settings for Gnp.
(In &gb namelist, surften (gamma) and surfoff (b) are used.)
I usually ask program to print out all temporary files for me during
MM/PBSA. There is one file _MMPBSA_info which contains all input
parameters. I checked this file and noticed that both surften, surfoff,
cavity_surften, and cavity_offset are listed. surften and surfoff are their
default values (according to Amber manuals under &gb section). I am a
little bit confused. So here _MMPBSA_info file just listed all parameters
but eventually if I specified &pb, then the program will only use
cavity_surften and cavity_offset for Gnp calculation, right? I want to make
sure I pass the correct parameters to the program...
Thank you a lot!
