CARBON WITH ANOTHER ELEMENT CHEMDOODLE UPDATE TO THE

Click , and click the sulfur atom. Click the new carbon atom to change it to an sulfur atom. Open the dropdown menu next to the element button, and select S. Answer: Click , and click the carbon atom. Four of them taking part in the carbon backbone and the other four.Note The question begins with the ChemDoodle Sketcher tool displaying a single carbon atom.

You may manually define group numbers for more advanced stereochemistry queries. All stereocenters are absolute ( abs) by default. You may now define enhanced stereochemistry for chemical structures, using or and & modifiers. Enhanced Stereochemistry.

Added a class (ChemDoodle.structures.Reaction) for defining a reaction and separating molecules into reactants and products based on an arrow object. Carbon has the highest valence 4 from those 3 elements in methanol. Please see the sketcher demo for more information.In some cases, the central atom can form more than other atoms connected to it.

Added a new demo to demonstrate our fully chemically aware and auto-calculating stoichiometry tables. Here are features to aid in ADA and WCAG compliance: ADA & WCAG Accessibility Compliance Added a new demo to demonstrate our chemical image recovery algorithms (also known as optical structure recognition): Chemical Image Recovery Input will automatically detect version and parse accordingly. You will set the version property of the ChemDoodle.io.MOLInterpreter class to true to output v3000 instead of v2000. Added MOL v3000 support, with enhanced stereochemistry support.

Carbon With Another Element Chemdoodle Update To The

Included are new features in the 2D sketcher improving user friendliness and adding more chemistry information. Corrected the display of implicit hydrogen overrides on metal atoms.Version 9.2 is a feature update to the ChemDoodle Web Components library. Improved isotope number spacing with respect to atom labels. Isotope popover now works properly on mobile devices.

The 2D sketcher now includes a new tool for editing isotope mass values to individual atoms. Coordinate covalent (dative) bonds are now supported in the ChemDoodle Web Components and may be drawn in the 2D sketcher. See the CursorManager class for more information. The default sketcher cursor is now a crosshair, which is optimal for drawing chemical structures. Custom cursors have now been implemented for all of the sketcher states, to give better feedback to users when using the 2D sketcher to draw figures. A couple shapes have been refactored, and those changes should be understood before updating if you use them.

You can now calculate molecule properties using a new demo created to show off the Cloud services which calculates many dozens of important descriptors. Our name to structure algorithms use OPSIN. This is in addition to structure to name.

The 3D editor open popup will now load both structures and shapes. Centering scenes in 3D components now modify a new parameter _Canvas3D.contentCenter, allowing us to relocate the camera instead of modifying the scene data. Give it a try using the Wiswesser Line Notation (WLN) demo, where we go over support for the latest v3.2 protocol and provide many examples. If you are interested in the history of cheminformatics, you can now recreate chemical drawings from Wiswesser Line Notation (WLN) codes using Cloud services. See it in action using the Calculate Molecule Properties demo.

Fixed bug where zero order bond tools incremented bond types in the sketcher. Fixed an error which prevented the sketcher's lasso tool from selecting content on mobile devices when no selection was present. If multiple molecules are present, they will be organized into a row.

The ChemDoodleWeb-libs.js file (which was removed in previous versions of the ChemDoodle Web Components) reference has been removed from the samples in the downloads.Version 9.1 is a follow-up revision, fixing a few minor issues found and adding in the maximumCommonSubstructure Cloud call. For more information, see the ChemDoodle JSON and 3D Shapes documents. The UnitCell class has seen a major refactor and now is initialized based on lengths and angles and an optional offset, instead of end points. The ChemDoodle JSON protocol has been adjusted accordingly, but 'DynamicBracket' will still be acceptable input. The DynamicBracket class has been refactored into the RepeatUnit class, to make it consistent with the desktop software.

There has been a complete refactor of the library to ES6 best standards. Corrected the zoom in and zoom out button directions in the EditorCanvas3D.Version 9 is a major update to the ChemDoodle Web Components library. Fixed bug where the help buttons in the UIs were not working. Fixed the zoom direction for the Transform3D canvas on mobile devices when using a pinch gesture. The Automatic Structure Grading demo exemplifies how this algorithm can be useful to a number of applications.

The strStartsWith() function in the Extensions package has been removed. Most importantly, we now use let variable declarations instead of var. The entire library has been refactored for ES6 best practices. The ChemDoodle Web Components website has been recreated to be responsive, much easier to read, and support high-DPI displays for clarity. New Cloud features include advanced CIP stereochemistry support, reaction equation balancing, and stereochemistry enforcement in mechanism matching.

The internal jQuery library has been updated to version 2.2.4. The 2D sketcher now uses SVGs for icons instead of PNGs, so they are crisp and clear on all devices at all resolutions, matching the graphics from the components. IE11 is still fully supported using certain internal polyfills, but we recommend IE users switch to Microsoft Edge. Legacy IE support (and Google Chrome Frame) has been dropped.

You can now resolve advanced CIP stereochemistry configurations using Cloud services. See the Styles tutorial for more information. The ChemDoodle.default_ specs have been replaced by a ChemDoodle.DEFAULT_STYLES Styles class object. The Canvas.specs parameter is now Canvas.styles.

We have added support to the Mechanism Matching demo to show stereochemical configuration enforcement in matching through our Cloud services. See it in action using the Balance Reaction demo. Our balancing algorithms can handle any input that can be balanced using a proprietary algorithm. You can now balance both drawn reactions and typed equations using Cloud services. See it in action using the Resolve CIP Stereochemistry demo.

Restored interactivity of the ChemDoodle Web Components on iPads using iOS 13+. Corrected the rendering of the wavy bond type. Adding lone labels would sometimes be impeded by dragging and moving the document, this is made easier by giving a 3 pixel leeway in dragging gestures before cancelling a lone atom placement. A proprietary feature has been added where if a text string is input with a space, then it will be rendered as typed, left aligned, instead of chemically formatted. See this Transparent Backgrounds tutorial for more information. This works for both 2D and 3D components.

Fixed issue where initializing a component over an existing canvas with defined size did not properly respond to screen DPI.Version 8 is the largest update to the ChemDoodle Web Components library to date. Fixed watermark rendering for EditorCanvas3D on high DPI devices. Fixed error in highlighing of the help button in EditorCanvas3D. Defined the button and table sizes for UIs so that they are not as vulnerable to external CSS. Fixed issue with UIs where the initial button selection would autofocus causing the webpage to load scrolled to the button. Fixed issues with loading optimized PDB files from Cloud services.

New 2D shapes include dynamic brackets, atom mappings and variable attachment points, while molecular surfaces (vdW, SAS, Connolly) can now be generated and rendered in 3D components. Condensed labels with abbreviations are now supported, for advanced chemistry.
