Hi, 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? Cheers, Joe Position of model2 (#20) relative to model1.pdb (#1) coordinates: Matrix rotation and translation 0.98820614 -0.14982292 -0.03165001 43.44553134 0.14930460 0.98862441 -0.01816347 -23.90940685 0.03401127 0.01322376 0.99933396 -9.65968865 Axis 0.10195507 -0.21328736 0.97165512 Axis point 180.93496764 275.63881775 0.00000000 Rotation angle (degrees) 8.85455905 Shift along axis 0.14318049
