[chimerax-users] Question about "color sample" command

[Tom Goddard]

Hi Sean,

  The "color sample" command is supposed to handle the situation where the map and or surface models have been moved in the scene.  This is a bug.  I fixed it today, in tonight's ChimeraX builds.

After I transform the volumes though if i re-issue the  "color sample" command it seems to color the first volume according to the values in the un-transformed second volume I am guessing?  Is this correct and expected or am I just doing something wrong? if this is what is happening is there a way to force color sample to read the transformed values or to re-sample the transformed maps so they are correctly read?
