Checker searches for aliases in the structure.
Fixers:
converting alias to abbreviated group if the alias value corresponds to a group in the abbreviated group list *  (aliastogroup);
converting alias to atom if the alias value corresponds to an element (e.g., Ar) (aliastoatom);
removing alias (revealing the atom under the alias) **  (removealias);
deleting the atom having alias information (removeatom).
Example :
| Alias Checker ( alias) | Warning: | Fix | |||
|---|---|---|---|---|---|
| Convert Alias to Group ( aliastogroup) | Convert to Atom ( aliastoatom) | Remove Alias ( removealias) | Delete Atom ( removeatom) | ||
| Detect Alias |  ex_alias_ch |  convert ot group |  convert to atom |  ex_alias_frem |  ex_alias_fdel | 
{primary} "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.
*User defined abbreviated groups are also available to be applied as recognizable abbreviated group set.
**Alias only covers the atom, and fixer removes this alias from the original atom.
{info} Alias atoms are not supported in the MolV3000 format. With file conversions from MolV2000 into MolV3000 format the alias info will be lost.
