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

Hi all, I'm looking at carbon bonded to benzene. The carbon can bond at all the equivalent carbon in the benzene, as well as several other places in my simulation. I am trying to compare structures by their RMSD, to determine the unique bonding structures. However, when I use OpenBabel the RMSD
