Dear Elaine, thank you very much for your assistance, but I do everything correctly, but it just did not work = see figure I would like to rotate tryptofan in my figure, so as first I need to set pivot on the C-atom (designated here as CB) and than rotate with right mouse the  tryptofan -- Martin Piskacek Laboratory of Cancer Biology and Genetics​ www.piskacek.org Department of Pathological Physiology Faculty of Medicine Masaryk University Brno Kamenice 5 625 00 Brno Czech Republic ---------- Původní e-mail ---------- Od: Elaine Meng <meng@cgl.ucsf.edu> Komu: <piskacek@post.cz> <piskacek@post.cz> Datum: 14. 7. 2020 0:29:28 Předmět: Re: [chimerax-users] re-assignment of mousemode "You have to display the atoms (e.g. command "show") and click on an atom. You said "on amino acid" which makes me think you are clicking on the ribbon instead, which is not the same as clicking on an atom and will not set the pivot. If you are displaying atoms and after clicking the Right Mouse "set pivot" icon, clicking the atom with the right mouse button doesn't make that atom the center of rotation, then you can use menu: Help... Report a Bug to submit a bug report that includes more information about your specific type of computer. If you don't want to show atoms, you can select ribbon of the amino acid with Ctrl-click (which will draw a green outline for that residue) and then use the Actions menu method described in my second message to set the pivot to the whole selected residue instead of to a single atom.

exactly all as you described all this is not working

I assigned what my wright mouse should execute, but if I try to apply this function on amino acid from my protein it is not working

Should I need to activate my mousemode somehow?

I suppose, that ChimeraX is not working properly on windows in my case I need some correction of some script to solve some hidden conflict in windows

Another way to set pivot (without changing mouse-button functions) is by:

(1) selecting an atom (Ctrl-click on the atom in the graphics window) that

you want as the center of rotation

(2) using menu: Actions... Set Pivot

Hi Martin, It is not clear what you mean by "no response." Do you have a mouse with a right button, or can you use trackpad + Alt as the right button? If you click any other icons in the Right Mouse tab of the Toolbar, can you successfully assign any of those other functions to the right mouse button?

...

Maybe it is a misunderstanding of how the icons work: If it is working correctly, nothing will happen when you click a RIght

Mouse icon, except that there will be a light green box around that icon. Clicking the icon only reassigns the function of the right mouse button, but does not perform any action at that time. However, if you reassign to pivot by clicking the Right Mouse pivot icon, for example, then later clicking with the right mouse button (if you have one) on an atom will make that atom the pivot point.

If you do not have a right mouse button, you can use the "mousemode"

command (instead of icons) to assign the function to a different mouse button.

as result is no response for re-assignment into Pivot or Rotate model

I tried ChimeraX versions 0,93, 1.0 and 1.1 (daily version) w/o improvement

Please, could you help me Thank you very much for support
