Hi Jared- I just use the C-alpha xyz coordinates and use d = math.sqrt(dx**2 + dy**2 + dz**2). I've been using python alone without pymol...using your code with the pymol api works for individual distances but I'm calculating hundreds of distances and need to write to a csv which does not seem to

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")[

2017-10-12 Thread Leigh M
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 -
