Unfortunately, the answers to both your questions is "no, it does not do what you want." First, the "Area/Volume from Web" tool only obtains the numerical values for surface area and volume; it does not get the volume map itself. Second, the qhull package is included for the Delaunay triangulation used by the "Intersurf" tool and there are no tools that use the Voronoi diagram capabilities. What type of visualization are you trying to create? Since Voronoi diagrams generate partitions separated by planes, do you want to see all the partitioning planes, or just polyhedra around specific atoms? We can look into whether qhull can generate the required data and how hard it would be to interface that with Chimera. Conrad Jean Didier Pie Marechal wrote:
Dear all,
We are trying to calculate voronoi's volumes around atoms in a protein. So far we used the interfase "Area/Volume from Web" but we have several troubles. So here the questions:
1. Is there a command line to do the server call automatically and display resulting volumes in the viewer?
2. We know that Qhull is one of the packages embedded in chimera. We try to see how to script voronoi calculation and read resulting volumes but failed so far. Do you have an example on how to generate the voronoi volumes maps from qhull in chimera?
All the best, JD
