[Chimera-users] measure rotation command questions

When I use the command 'measure rotation' I get a matrix in the reply log.

1) The fourth column is 'translation'. At most the translation I see is 
5 Angstrom, so how do I get these numbers (see below)? I also have a 
shift along axis reported, which seems a more reasonable number, but 
what if the shift is in a a different vector to the axis?

2) I can get depiction of the rotation axis, but can I also get a 
depiction of the translation vector?



Position of model2 (#20) relative to model1.pdb (#1) coordinates:
   Matrix rotation and translation
      0.98820614  -0.14982292  -0.03165001  43.44553134
