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?
