[Chimera-users] radial density map

Chimera does not make radial density plots. I guess you found the RadialDensity.zip extension which creates the “rd” shortcut on the Chimera scripts web page
There is an old mailing list message I wrote about that extension
which says that it prints to the Chimera reply log the average radial density as a function of distance from the center. Make sure your map origin is at the center of the virus (volume dialog menu Features / Coordinates, Origin Index value). You can plot that data in any graphing program. Each value is the average over a thin spherical shell so it does not depend on any axis. This won’t help you if you just want the density on a 1-dimensional line coincident with a symmetry axis.
