paint_ramp [property] [min_value max_value] [start_colour] [end_colour]
Colour ramp according to the individual value of the property. The default property is the residue internal number, stored as a datablock with a residue property [mol]_residue_irc. If this property does not exist, it is created. The minimum and maximum values are those in the specified property vector. This option can be used make pretty CA drawings where the colour changes as one goes from N-terminal to the C-terminal:
paint_ramp ; ; red blue ca ; end
We could also ramp according to temperature factors, so that the smallest values are blue and the highest values are red:
paint_ramp atom_b ; violet red zone ; end
or we could colour the real space residue fit from salmon pink to cyan:
paint_ra res_rsfit ; salmon cyan z ; end
