<p><b>New page</b></p><div>If the '''mesh_negative_visible''' setting is '''on''', then an [[isomesh]] at iso level 3.0 will in addition show the -3.0 contour. The color of the negative contour is defined by the '''mesh_negative_color''' setting. The color of the positive contour is defined with the [[color]] command, or with the [[mesh_color]] setting.<br />
<br />
The '''surface_negative_visible''' and '''surface_negative_color''' settings control the same behavior for [[isosurface]] objects.<br />
<br />
Since PyMOL 1.8.4 the negative color can be controlled from the color menu ("C > negative > ...").<br />
<br />
== Example ==<br />
<br />
Show the +/- 3 sigma iso-level mesh ("wire-frame") of a difference density map.<br />
<br />
fetch 1ubq, diffmap, type=fofc, async=0<br />
isomesh diffmesh, diffmap, 3.0<br />
color green, diffmesh<br />
set mesh_negative_color, red<br />
set mesh_negative_visible<br />
<br />
Same, but with a closed surface:<br />
<br />
fetch 1ubq, diffmap, type=fofc, async=0<br />
isosurface diffsurf, diffmap, 3.0<br />
color green, diffsurf<br />
set surface_negative_color, red<br />
set surface_negative_visible<br />
<br />
