• Checker searches for atoms having query properties. Tick options for searching:

  • Hydrogen Count (:H=true);

  • Connection Count (:X=true);

  • Ring Bond Count (:rb=true);

  • Ring Count (:R=true);

  • Implicit Hydrogen Count (:h=true);

  • Smallest Ring Size (:r=true);

  • Aromaticity (:a=true);

  • Substitution Count (:s=true);

  • Unsaturation (:u=true);

  • Explicit Connection Count (:D=true)

• Fixer: removes the identified query properties (removeatomqueryproperty).
