Contract S-groups

This action contracts S-groups to their abbreviation. The action will not be performed on S-groups listed in the Exclude attribute. S-groups names should be listed in the Exclude attribute and be separated by commas (e.g.,contractsgroups:Exclude='Ph,Ac').

Example :

Action	Input	Output
Contract S-Groups (contractsgroups)	Contract group input	Contract groups
Contract S-Groups excluding "Ph","Ac" (contractsgroups:Exclude='Ph,Ac')	Contract group input	Contract groups w excluded lsit

Contracted S-groups can be easily displayed again in the molecules by using Expand S-groups action.

To completely remove S-groups from molecules, use Ungroup S-groups action.
