Coot? Measure angle I assume you just want that value and not a script to run for multiple occasions? Jürgen

First, I tried the easier ways. I presume these two aromatic rings are in the perfect planes, that is why I tried plane_wizard.py and draw_plane_cgo.py which work very well. However after I got two plates by plane_wizard or draw_plane, I don't know how to measure the angle between these two plates. I also don't know whether I could get the angle I wanted from these two ways. I tried vector_angly.py which cann't loaded into pymol properly. If it could, how can i do to get the angel from these two plates I drew. Solutions? Since I am in the beginner state, please show me details which i could follow step by step. Second, If these two aromatic rings are not in the perfect planes, how can i find the best fit planes? And then find the angle between the best fit planes? I tried svdplos.py and makeCGOplates.py which are downloaded on line. unfortunately both of these can't be loaded into pymol properly. Solutions? Thanks! Bing Wang
