In Chimera, there may not be commands that do exactly the same thing as some button. You might look at "focus <model-number>" and "reset" (maybe only if one model is open, or they haven't been moved relative to one another?) but in my tests, they did not do exactly the same thing as those buttons. That's one reason ChimeraX is way better than Chimera! You can use the GUI and it shows the command that it used in the Log. Best, Elaine ----- Elaine C.

Dear Chimera,

What would be the equivalent commands to the Center and Orient buttons at the bottom of the Volume Viewer menu tab?

Thanks

Hi Hernando, Here is how to apply symmetry to one copy of an atomic model in a symmetric cryoEM map in ChimeraX. First use the "measure symmetry" command to determine the map symmetry, then use the "sym" command to make the symmetric copies of the atomic model. Here is an example open 8ofx open 16862 from emdb measure symmetry #2 set true sym #1 symmetry #2 Tom

Thanks Elaine,

I will try to do this with ChimeraX. What I am trying to to do is to generate symetry related copies of a model fitted into a density map using the sym command. I noticed that the only way to define the center of symetry to be centered on the density volume was using the option center #n (where n is the id of the voume density) but only after doing center and orient by pressing the buttons in the volume viewer.

Although chimeraX is much more prowerful I still find hard to find the the equivalent in ChimeraX of some operations that I use often in Chimera. 😉

Thanks again,

Best

H.
