Then you can color using that distance. Here’s an example set of Chimera commands. open 1mtx show open mean_distance.py rangecolor distance_from_mean 0 blue 3 white 6 red The script uses all open molecules as the ensemble. The coloring can also be done with menu Tools / Depiction / Render by Attribute. Tom
