Nearest neighbour, nnn....etc. of an atom in a crystal

[qnach]

There are some software can provide visualization of crystal or protein structure, i.e. VESTA.
I want to know how many atoms is the nearest neightbour (and their distance), and the next nearest neighbour...etc of a particular atom.
Is there any software (or perhaps some data book?) can do this?

The standard software for looking at protein crystal structures is PyMol: https://www.pymol.org/

You can measure distances with the "distance" command, and find atoms neighboring a selected atom using the "around" command:

Thanks, I have got this program. Could it also be used for crystal structures?
But don't know how to exits from it, except restart my computer...
It is not a window version. Perhaps evolved from some program 20 years ago and still in command mode...
