Dear Chimerax community,

I have a molecule that has a clockwise directionality for some cryoem maps, and a counter-clockwise directionality for some maps. I see this difference in directions even after fitting each map with the fit #1 in #2 command, and am now trying to build in each map. In order to create a PDB file with both directionalities, I used PyMol to do alter_state 1, obj, y = -y, rebuild, and then exported the new molecule. Is there a command in Chimera or Chimerax to do the same operations? I tried using matrix invert to no avail.

Sincerely,

Mrinalini
