Improvements

• A list of excluded atom labels can be specified for Pseudo Atom Checker.

Improvements, deprecations

• Wedge Error Checker was replaced by Incorrect Tetrahedral Stereo, Non-standard Wedge Scheme , and Non-stereo Wedge Bond checkers.

• Wedge Error Checker is deprecated.

Improvements

• Additional improvements in Wedge Error Checker and Clean Wedge Fixer.

API changes

• chemaxon.checkers.runner.BasicCheckerRunner was removed from the public API. Use AdvancedCheckerRunner.

Bugfixes

• Wedge Error Checker didn't detect non-stereo wiggly bonds.

Improvements

• Clean Wedge Fixer converts non-stereo wiggly bonds to single bonds.

Bugfixes

• Solvent Checker threw exception if input molecule couldn't be converted to SMILES format.

New features

• New checker: Brackets Checker .

Bugfixes

• Wedge Error Checker didn't always agree with Wedge Clean Fixer. From now on the molecules fixed by Wedge Clean Fixer are accepted as correct by Wedge Error Checker.

Bugfixes

• Bond Angle Checker did not accept some bond angles as correct. Bonds connected to a ring were affected.

Bugfixes

• From now on Rare Element Checker will not detect deuterium (D) and tritium (T) as rare element.

Bugfixes

  • removes superfluous attachment points,

  • can fix errors in R-group definitions having multiple equivalent candidates for the addition or removal of the attachment point(s),

  • can fix structures containing contracted abbreviated groups,

  • can handle R-group bridges.

Bugfixes

• Circular R-group Reference Checker failed to identify some circular references

• Missing R-group Checker did not identify unnumbered R-group as missing

New features and Improvements

• OCR Error Checker was improved, now it identifies optical structure recognition errors better

• "Discard OCR errors" option was removed from Structure Checker application and structurechecker command line application. Use OCR Error Checker.

Bugfixes

• Overlapping Bond Checker detected some non-overlapping bonds as overlapping [error report]

New features and Improvements

• Less invasive fix of bond length errors and bond angle errors with newly introduced Bond Length Fixer and Bond Angle Fixer.
