• Checker searches for aliases in the structure.

• Fixer offers:

  1. converting alias to abbreviated group if the alias value corresponds to a group in the abbreviated group list * (aliastogroup);

  2. converting alias to atom if the alias value corresponds to an element (e.g., Ar) (aliastoatom);

  3. removing alias (revealing the atom under the alias) ** (removealias);

  4. deleting the atom having alias information (removeatom).

Example :

Note : "OMe" and "CL" were defined as alias. After converting "OMe" to methoxy group, the abbreviated group is linked correctly to the chain, i.e., bond through the oxygen atom.
^* Note : User defined abbreviated groups are also available to be applied as recognizable abbreviated group set.
^** Note : Alias only covers the atom, and fixer removes this alias from the original atom.
