Re: [PyMOL] Electron density map color

[Thomas H. <tho...@sc...>]

Hi Vatsal,

This is how you show positive and negative contour:

fetch 1ubq, diffmap, type=fofc, async=0
isomesh diffmesh, diffmap, 3.0
color green, diffmesh
set mesh_negative_color, red
set mesh_negative_visible

Example copied from:
https://pymolwiki.org/index.php/mesh_negative_visible

Cheers,
  Thomas
