Non-standard Wedge Scheme
Non-standard Wedge Scheme checker tries to identify valid, but non-preferred wedge bond depictions according to the IUPAC recommendations. .
Checker detects wedge configurations not following the IUPAC recommendations
Fixer: rearranges the wedge bonds.
Example :
Non-standard Wedge Scheme Checker ( nonstandardwedgescheme)Warning: Fix Rearrange wedges ( rearrangewedges)Non-standard Wedge Scheme 
Non-standard Wedge Scheme (Incorrect Tetrahedral Stereo
)
The Non-standard Wedge Scheme checker is triggered and the "rearrange" fix is applied only when the stereo info can be calculated.
