There is one polypeptide molecule solvated with water molecules.

I would like to select the water molecules only within certain distance from
the polypeptide.

I found that we can use 'within' command, but I couldn't make it.

The manual says it can be done by the command "within <distance> of
<molecules>", however it's not clear for me when this command should be

Could someone tell me how to do this? (e.g. What should be done first,
seconde and so on)

Thank you.
