Hi Qiancheng Xia, Please use the chimerax-users@cgl.ucsf.edu address (CC'd here) for ChimeraX questions so that people don't get mixed up between Chimera and ChimeraX. Chimera does not have the reportMatrix option. As for ChimeraX, you didn't show the exact command that you tried so I can only guess what went wrong. My guess is that you need to include "reportMatrix true" not just "reportMatrix" <https://rbvi.ucsf.edu/chimerax/docs/user/commands/matchmaker.html#options> I hope this helps, Elaine ----- Elaine C.

Hi, I want to use chimera to obtain the transformation matrix between two protein structures. I know that matchmaker can superimpose them together, but I still want to obtain the transformation matrix. I've noticed that matchmaker in chimerax (https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/matchmaker.html) offer a keyword "reportMatrix" to do that. But when I use that keyword in chimerax, "Expected a keyword" will be returned without match or a matrix. With Regards,
