[chimerax-users] Colour residues by local resolution estimation map

[Tom Goddard]

Hi Yiannis,

  I added a "measure mapvalues" command to ChimeraX, in tonight's build (dated May 20) that allows you to interpolate a local resolution map at atom positions and assign the interpolated value to each atom.  Then the "color byattribute" command can do the coloring you want.  For example, if your local resolution map is #2 and your atomic model is #1

	measure mapvalues #2 atoms #1 attribute "resolution"
	color byattribute "resolution" #1 palette 3,blue:4.5,white:6,red key true

The color command will color the atoms and each residue in a ribbon using the average resolution value for that residue's atoms.  See the color command documentation for more details
