Dear experts,
I have two questions to ask.
a) I tried to calculate water diffusion in hydrated bilayer system using
two commands from ambertools14, *diffusion* and
*stfcdiffusion.*
I understand the *diffusion* command does calculate the average of movement
of every atoms in a molecules frame-wise. While the *stfcdiffusion* command
calculate the diffusion of center of mass (COM) of molecule's atoms in a
system
I wish to know which method is more appropriate to use in a reasonable way?
b) In a hydrated lipid bilayer system, do we calcualte the water diffusion
in 2D (x-y) or 3D (x-y-z)?
Thank you.
Vijay
