Hey, I'm not the only one who answers these questions! :-) It is explained in the "Fit in Map" manual page: <https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/fitmaps/fitmaps.html#matrices> "The transformation matrix of the fit model relative to the reference map is reported in the Reply Log. The first three columns of the matrix describe a rotation and the fourth describes a translation (performed after the rotation)." I hope this helps, Elaine ----- Elaine C.

HI Elaine, I want to know the rotation and translation components along x,y and z separately from the rotation matrix obtained from chimera reply log upon fitting a model into a map. Will it be possible to know?
Matrix rotation and translation 1.00000000 -0.00000000 -0.00000000 1.83458738 -0.00000000 1.00000000 -0.00000000 1.15016978 -0.00000000 -0.00000000 1.00000000 -0.53835221 Axis 0.00000000 0.00000000 1.00000000 Axis point 0.00000000 0.00000000 0.00000000 Rotation angle (degrees) 0.00000000 Shift along axis -0.53835221
