I've also got http://baoilleach.blogspot.co.uk/2012/01/whats-up-dock-calculate-rmsd-between.html where you want the RMSD without alignment (but still need automorphisms for the mapping). I'll see if I get a chance to do this today... On 1 August 2017 at 16:09, Geoffrey Hutchison wrote: >> I sho

Thanks for the quick reply. This feature would be extremely useful. I think it is a graph isomorphism problem. I’m not following the first method that you proposed. But the second method you mentioned definitely works. In my case, I need to shuffle the atoms of the benzene such that they ro

I should probably add this feature. In the meanwhile, one way would be to generate canonical labels and then shuffle the atoms of both into that order. Alternatively, if there's a way to get the mapping between two molecules, you would just need to shuffle the atoms of one of them. (on my phone so
