In the column Remove is possible to select the nodes/atoms to be removed
WARNING: it is better to make a duplicate of the structure in use before doing any simplification; the process is irreversible.
Press Ok and be sure that the 2-coordinated nodes are contracted. The resulting net is a partial ring net with respect to the simplified net in the standard representation since its nodes correspond to some rings of the initial net. Pay attention that both standard representation and the partial ring net are 4- coordinated, but have different topologies that will be proved in Module 5. See Appendix 2 for details and definitions.
Tips: The Compound/Auto Determine/Simplify Adjacency Matrix procedure is a very useful
procedure to be used quite often, even at the beginning. It is always easy to look at a molecule if all the
dangling atoms (1-connected) are removed. So, after all the bonds/contacts/H-bonds are found via
AutoCN , it may be useful to duplicate your structure and simplify it. The IsoCryst representation will be
more legible. See for example the simplified picture for XEHKIE (with some bond/color changed... try!),
the complex 2,3,5,6-tetrachloro-trans-1,4-diethynylcyclohexa-2,5-diene-1,4-diol C10H4Cl4O2 is
represented by a much simpler C6(OH)2.
