- Checker searches for brackets. Brackets are usually associated with generic S-groups.
- Fixer offers removing brackets (removebrackets).
Example :
| Brackets Checker (brackets) | Warning: | Fix |
|---|---|---|
| Remove Brackets (removebrackets) | ||
| Detect brackets |  |

Note: Checker does not detect brackets denoting polymers and mixtures. Graphical brackets (brackets not related to S-groups) are not detected.
