[Chimera-users] Showing inertia axes

[Tom Goddard]

Hi Guiseppe,

  I guess you are using the Chimera "measure inertia" command to show an 
inertia ellipsoid for specific atoms.  There is not an option to show 
the principal axes as arrows.  I'll add that to our feature request 
list.  But you can do it now by hand if it is worth going to that 
trouble.  You would use Chimera BILD format to draw the axes as in the 
following mailing list message

    http://www.cgl.ucsf.edu/pipermail/chimera-users/2009-April/003762.html

but you would use the axes that the measure inertia command reports in 
the reply log.

The ellipsoids are shown in the graphic window as a surface model and information about each ellipsoid are given in the reply log. In it the ellipsoid vectors are reported among others info. I wonder if you have a command to show vectors defining the ellipsoid instead of the surface model in the graphic window.
