Hi Paul,
Hi Paul,
I suggested adding the path to sys.path in your Chimera start-up so that you wouldn’t have to modify the system Python.
Here is a Python example of computing a triangulation for the part of a plane inside a closed surface, using as an example an icosahedron for the closed surface. You can just use File / Open… in Chimera to run it and it will report in the Reply Log (menu Favorites)
Clipped icosahedron, clip plane has 10 triangles
More Python code examples are on the Chimera Python scripts web page:
The Chimera programming documentation is scant. To figure out how to write the attached example code I looked at my Chimera distribution at file
Chimera.app/Contents/Resources/share/SurfaceCap/surfcaps.py
at the calculate_cap() routine. All of the Chimera Python modules are in the above “share” directory — it is useful to poke around in there to figure out how things work, although it can be hard to find what you want.

Thank you very much, Tom.
I found the folder and added a file 'chimera.pth' to system Python site-packages with the path to Chimera's site-packages, which also did the same thing.
The whole point for me doing this was to try and take advantage of Chimera's functionality. I would like to slice closed 3D volumes. I've looked through the online documentation but have not had success. Could you please point me in the right direction on how to achieve this?
My input will be vertices and polygons together with a slicing plane and my expected output is the contents of the plane as an 'image' or set or polygons.
Many thanks.

Hi Paul,
The error means that you have two different colorbrewer Python modules and Chimera is getting the one that didn’t come with Chimera. I see the Chimera colorbrewer.py file in
/Applications/Chimera.app/Contents/Resources/lib/python2.7/site-packages/colorbrewer.py
But I’m guessing you have the following colorbrewer module which is completely different from the Chimera one installed with your system Python
In order for Chimera modules to work from the system Python it will be necessary that Chimera finds its own Python modules. So you should put the above Chimera site-packages directory in front of Python system locations in the Python search path sys.path. I would put this in your script that starts Chimera using the system Python, something like
import syssys.path.insert(0, '/Applications/Chimera.app/Contents/Resources/lib/python2.7/site-packages’)

Hi,_______________________________________________
I want to use the chimera API and I've managed to configure a successful import of chimera except that I get that colorbrewer is not installed.
>>> import chimera
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Applications/Chimera.app/Contents/Resources/share/chimera/__init__.py", line 73, in <module>

from colorbrewer import ColorBrewer
ImportError: cannot import name ColorBrewer
What is the right way to go about this? (I could create a symbolic link to my system colorbrewer, but that doesn't seem clean).
