[Chimera-users] Radial density plots

Hi Pranav,

  The Chimera radial map density code I gave to Padma (in 2007) was a 
simple Chimera extension in a directory called RadialDensity. You either 
put the RadialDensity directory in the chimera/share directory (on Mac 
Chimera.app/Contents/Resources/share) or you can put it somewhere else 
for example /Users/me/chimera-stuff/RadialDensity then add the parent 
directory (e.g. chimera-stuff) using Favorites / Preferences, category 
Tools, Add....  After doing either of these install steps Chimera will 
have a keyboard shortcut "rd" that prints the density values as a 
function of radius (in steps equal to the map grid spacing).  You can 
plot those with whatever plotting application you want.  To run the 
shortcut you can use the command "ac rd", or enable keyboard shortcuts 
(using Tools / General Controls / Keyboard Shortcuts) and just type rd.

   I've put the RadialDensity extension on the Chimera Python scripts 
web page.


I've attached a plot I made with it of a bacteriophage (EMDB 1011).
