Did you know...



distance creates a new distance object between two selections. It will display all distances within the cutoff. Distance is also used to make hydrogen bonds. Calling distance without arguments will show distances between selections (pk1) and (pk1), which can be set in editing mode or using the PkAt mouse action (usually CTRL-middle-click).

Note: For interactive use, the measurement wizard (from the PyMOL menu) makes measuring distances easier than using the distance command.
If you want to measure distance and avoid creating a distance object, use Get Distance or Distancetoatom.

Example of distance.  See example #1.

Example of distance.  See example #2.


distance [ name [, selection1 [, selection2 [, cutoff [, mode ]]]]]
