[Chimera-users] Map Orientation for Symmetry Plug-in

I am using the Symmetric Molecule Copies plug-in with Chimera.
I am wondering if there is a preferred way to orient an EM volume so
that it is centered around the z-axis at the origin. From my
experience with this plug-in, symmetry related molecules are
generated around z-axis at the origin of the viewing area. I am
finding that my maps tend to be close, but not exactly oriented
around the z-axis for a helical volume. Molecules fit into a portion
of the map then tend to have slightly askew symmetry mates relative
to the volume (presumably because the z-axis of the map is not
exactly oriented along the origin of the symmetry z-axis).
After playing around with various map tools (MAPMAN, Priism), I am
still not satisfied with my orientation protocol and wonder if anyone
can suggest a tried and true method for this.
