Hi Leon, Sorry for the slow reply. Greg has just merged in an updated C+ document which will be available in the new release. If you've used the old methods for iterating over atoms, you might want to take a look at that bit at least. It is now vastly simpler. It seems the RMS routines in C++ are still waiting for someone to be stirred enough to do them. I'm not sure they will make your life much faster in any case, as it is an inherently expensive process and the basic comparison of 2 conformers is compiled C++ code wrapped up for Python. What the Python wrapper has that isn't in C++ is just a higher-level function that does all conformers vs all conformers for a molecule. The overhead for those extra loops in Python is unlikely to be huge, I wouldn't think. Best, Dave
