[gmx-users] Re: genbox -shell

[Dongsheng Zhang]

Dear David,

Thank you for your reply. My input box is pretty large. The dimensions
are: 9.46000   6.52700  14.59200. They are generated by 

editconf ... -c -d 1.0

the thickness of my shell is 1.0, I think it is large enough for those
water molecules. Most water molecules are inside the shell, only those
three are far way.

If you need more information, please let me know!


Best wishes!
