Friends,<br>I have two ligands with a common benzoxadiazole ring. I want to do the rmsd comparison only on the ring, but the names of the atoms forming the benzoxadiazole ring are different in both the ligands. <br><br>Is there any way to use ring name as a string the compare the rmsd. ie. rmsd of benzoxadiazole of ligand 1 and benzoxadiazole ring of ligand 2<br>
