Dear all,
As a test run, we are trying to compute diffusion constant of water.
We have taken 64 water molecules. I am confused about the "center" and
"image" command. Using the following command, we are getting the value
2.918 and without using the two commands we are getting a different
value (2.026). kindly suggest.
trajin X.mdcrd 1 last 1
unwrap :1-64
center :1-64 mass origin
image origin center familiar
diffusion 0.25 diff.out :1-64 average
go
