Dear all,

I want to visualize solvent distributions (i.e distributions of the first
water shell) around one solute molecule.

So I executed the following grid command within ptraj

 

trajin md.crd

center :1

image

rms first mass out rms :1

grid wat.xplor 100 0.5 100 0.5 100 0.5 :WAT

 

Then I got the wat.xplor file and visualized the file with chimera soft
ware. (attached files)

But I doubt that I could get the figure I would intend.

 

Actually I can't understand grid command and the ouput file( wat.xplor file
)

I don't know how I should deside the value of grid point and grid space.

Could you give me any help?

 

Tnanks
