P.S. “vop new” is a relatively recent addition, so you would need to have Chimera version 1.11 or newer to use that command

If you were careful to rotate only your virus map, then the new dummy map would still be aligned with the displayed axes. However, you’d have to create the new map so that it encloses your existing rotated map (show box outlines with Volume Viewer).

I used “activate only” to manipulate the volume relative to the axis.bild object. After rotating the virus to align the tail to the Z-axis, I try to save the map but it’s always back in the original position when I re-open it in Chimera. Is there a way to save this transformed map?
