Hi Alicja,

  runCommand() invokes typed user commands and does not return values and unfortunately the measure distance code in


(the distance() and report_distance() functions) are not well written for calling directly from Python.  Your best approach would be to copy the distance() and report_distance() functions from measure.py and modify them to actually return the distance values you want.

I need to measure distance between an atom and a density map and keep it in a variable, so I'm trying to get a value from "measure distance" command in Python, but unfortunately with no results. Is there any way to somehow get it into a variable?
