[Chimera-users] Reset surface programatically from python

[Tom Goddard]

Hi Thomas,

	You need

mod.show()

to have the density map recompute its contour surface.   You can remove the mod.display = True line.  Your code 

mod.surface_levels = [-1,0]

is setting two contour levels one at density value -1 and one at 0.  Is that what you intend?  If you only wanted a single level you would use 

mod.surface_levels = [-1]

  Tom
