Hi Leigh -
How are you getting the coordinates? This works for me:
```
import math
# Show more digits for the distance label
set label_distance_digits, 10
# Make an alanine residue
fab A, ala
# Get coordinates from 2 atoms
o = cmd.get_coords("/ala///1/O")[0]
h = cmd.get_coords("/ala///1/H")[
yep!

You are using d = sqrt(dx^2 + dy^2 + dz^2), right? (Where dx = x2 - x1,
etc.)

Anyone know how pymol calculates distance between two atoms?
I wrote a python script that calculates distance using the distance formula
and the xyz coordinates in the pdb, and it differs from the wizard by ~40%.
Any ideas on what might be going on would be helpdul
Thanks!
Leigh
