Hi Henning, Best to share with the list (cc'd here)... One problem with the solid level is that the second number should be between 0 and 1. However, even when I tried that, I got the same error, so I'm guessing that is a bug. The second issue may also be a bug: I don't know why the style does not change directly between surface and mesh. I'll try a simple test case and submit a bug report for that one too. Sorry for the problems, Elaine ---------- Elaine C.

Hi Elaine,
Yes, you are right with the solid level option. But I still don't understand this. This here doesn't have any effect, I give the command on the command line: volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style surface No change of display. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style mesh No change of display. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style surface No change of display. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style mesh No change of display.
This leads to an error message in the log window: volume #5 level 2.30,2.6 color 0.6,0.6,0.6 transparency 0.4 style solid No change of display. Error message: TypeError: 'NoneType' object is not iterable File "/Applications/Chimera.app/Contents/Resources/share/VolumeViewer/solid.py", line 213, in update_coloring cmap, cmap_range = self.colormap()
(I just submitted a bug report on the above.)
And this gives an error message after the "solid" command, but after that the other commands appear to work: volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style solid Solid level must be <data-value,brightness-level>; no change of display. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style surface The display changes to surface view. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style solid No change of display. Error message: Solid level must be <data-value,brightness-level> volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style mesh The display changes to mesh view. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style solid No change of display. Error message: Solid level must be <data-value,brightness-level> volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style surface The display changes to surface view. volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style solid No change of display. Error message: Solid level must be <data-value,brightness-level> volume #5 level 2.30 color 0.6,0.6,0.6 transparency 0.4 style mesh The display changes to mesh view.
Do you have an example how to change the display from "mesh" to "surface"?
Thanks for your help so far,
Henning.
