Hey, I'm not the only one who answers these questions! :-) It is explained in the "Fit in Map" manual page: <https://urldefense.com/v3/__https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/fitmaps/fitmaps.html*matrices__;Iw!!JqxBPMk!xxVnA8H7hYuofVFeoHwHPo-TJhHwl52Ro3yS2YPnrup56wIKqpeuq-rtH-PilKRZ3g$ > "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.
