• Checker searches for abbreviated groups in the structure*. Options:

  • expanded (:expanded=true);

  • contracted (:contracted=true);

Default and custom abbreviations are also possible to set. The excluded list elements are case sensitive and should be separated by commas (,). (:excluded=Ph,Ala,Gly,MyGroup)
