Hello,

I would like to measure distances between atoms in a structure by using the command line, and not manually by clicking on the atoms and then clicking on "create" button in the Structure Measurements tool.

I would like to map many distances on the same structure (I performed a crosslinking experiments, so I would now like to map the crosslinks on the structure of my protein of interest).

I tried something like distance #1 :347.A@ca - :323.A@ca and similar variations, hoping that I could get the distance between CA atoms of residues 347 and 323 of chain A (there are 12 chains in my protein) from model 1. But I couldn't find a good combination of commands to give me a distance.

I would highly appreciate any advice. Otherwise, I would have to map manually over 20 crosslinks for each chain... 

Thank you in advance,

Iva
