Limitations of the Open Babel SMARTS Implementation

The Open Babel implementation of SMARTS is not bug-free, nor does it support everything in the Daylight Toolkit. In particular, it does not currently support:

• Component-level grouping (i.e., "(C).(C)")
• Use of non-tetrahedral chirality

This list may not be complete. Please e-mail the <a href="mailto:[email protected]">openbabel-discuss</a> mailing list if you have questions about the SMARTS support in Open Babel.
