Substructure

• Checker searches for SMARTS defined substructures. Substructure Checkers can be set individually.

• Fixer: when the substructure is specified as reaction SMARTS or SMIRKS, the checker works as fixer as well.

  Example :

  Substructure Checker	Warning:	Fix
  		O=N=O>>[O-][N+]=O
  Checker setting : SMARTS: O=N=O>>[O-][N+]=O	substructure_nitro	substructure_fixed

  Note : You can rename "substructure checker" in Structure Checker GUI. Click on the name field of the configured checker and rename it by typing a new name. For example, you can name it as Nitro Checker.
