![]() ![]() This ability is off by default when creating a highlight. Highlight shapes now allow you to color in rings.On input, non-integral groups from ChemDraw are not fully compatible with the z-indexing system in ChemDoodle, so there is a new option in Files Preferences for ChemDraw files to breakup groups on input, preserving the intended z-indexing. Support for the input and output of group objects to ChemDraw CDX and CDXML files.Using shortcut keys to add chains will also look for the least congested area, like the optimize zone does. When using shortcuts to add chains, if the origin is an end of a triple bond, the angle will be made 180 degrees. Improvements to the automatic chain drawing tools.Unsupported configuration types will just be ignored, but will show a warning in the Line Notation Pad widget. Advanced parsing of all configuration types, even those not supported by ChemDoodle. Allene and cumulene configurations are now supported. Reworked and full support for advanced stereochemistry in SMILES input and output. ![]() ![]() Reaction SMILES are now read and written. Atom properties are now interpreted as best as possible if not in the correct order as defined by Daylight. Please see section 13.17 of the ChemDoodle User Guide for more information. More stereochemistry warnings are now shown, including on bonds, to check your work. Interpretation of wedge drawings is also accurate via IUPAC rules. It now works closely with the 2D layout algorithm and produces accurate wedge diagrams according to IUPAC rules, even in complex cases. The stereochemistry engine has been rewritten from the ground up.Try your hardest structures and let us know what you think! Standard molecule type orientations (amino acids, steroids, etc.). Further advances for the 2D structure layout algorithm.For macOS users, the QuickLook plugin is now functional on the latest macOS versions. New features include ring coloring for highlights, support for group objects in ChemDraw files, checking bonds for drawing warnings, new periodic table options and more. Further advancements in our industry-leading 2D coordinate layout algorithm are provided. The stereochemistry engine has seen a complete rewrite, with a brand new system for evaluating stereogeometries in OD/2D/3D, leading to accurate generation and interpretation of wedge drawings and full support for stereochemistry in SMILES protocol. When copying text, plain text output will now properly include spaces.ĬhemDoodle 2D v11.10 includes further advancements to our cheminformatics functions along with some new features.Fixed error where copying text from labels sometimes did not work.Corrected elemental analysis m/z calculations when multiple isotopes of the same type are present.Corrected bug where molecules with condensed labels were displaying stereo descriptors on the wrong atoms/bonds.Improvements for the input/output of implicit hydrogens in labels concerning ChemDraw files.Added support for dative bond types in MDL/BioVia formats.This option is found in the Preferences window, under the Files>Formats>Chemical>MDL Connection Table Files section. Added option to output MDL CT atom stereo parity.For thorough information, please see section 13.17 of the ChemDoodle user guide. Projection interpretation may be disabled in the Preferences window under the Functions>Tools>Stereochemistry section. You may use the force stereochemistry functions on properly drawn projections, and a helpful error message will display if ChemDoodle cannot force the desired configuration. Fischer, Haworth and chair projections are supported. Projections drawn in ChemDoodle will now be automatically recognized and stereochemical features may be analyzed.Stereochemical projections will now be automatically recognized and stereochemical features will be analyzed. ChemDoodle 2D v11.11 is another feature update focusing on our main topic this year, stereochemistry. ![]()
