Dear all,

I would like to use SMARTS/SMILES to find specific groups of atoms but I 
am not sure about how to analyze and use the results.

Let's s say I want to find all cycles within a structure and then use 
the center of mass of each cycle to do a further analysis with each cycle.
I could run the following command:

   x = {*}.find("SMARTS","[r]")

But then there is just a list of atoms in 'x' and I don't know which 
atom belongs to which cycle.

Q: Is there a way to preserve the grouping defined by the SMARTS string 
within a search result?

Q: Or do I have to loop through all atoms in the result list and search 
again somehow for each atom to find the other atoms belonging to it's group?

Regards,
Rolf
