What’s New
The latest release of Signals brings improvements to the ChemDraw+ application. This release brings enhancements to the drawing experience including the introduction of a new context sensitive toolbar in the drawing editor, monomer searching in the HELM editor, and highlight coloring options. Additionally, import/export support has been expanded. Finally, we have also fixed a small number of bugs.
The following improvements are available for users of Signals ChemDraw. Certain features may only be available with enablement by an administrator.
ChemDraw+
- New context-sensitive ChemDraw floating toolbar
- RXN file support in the ChemDraw editor
- Turn on atom numbers for chemical objects
- HELM editor now supports monomer structure searching
- Highlight coloring now available
- Notebook descriptions are now viewable in the application
- Import & Export options have expanded
ChemDraw+
New context-sensitive ChemDraw floating toolbar
A context-sensitive floating toolbar is now available in the ChemDraw editor. When objects are selected on the ChemDraw canvas, a toolbar appears above the selection, displaying commonly used tools based on the selected object. As the pointer moves away from the toolbar, it automatically hides to minimize disruption to the editing process.
RXN file support in the ChemDraw editor
RXN files can now be dragged and dropped onto a ChemDraw canvas and converted automatically to cdxml for continued editing.
Turn on atom numbers for chemical objects
Atom numbers in ChemDraw can now be enabled for a selected object by selecting 'Show atom numbers' in the Atom section of the Properties panel.
HELM editor now supports monomer structure searching
The HELM editor now supports structure-based monomer search alongside text search, using a new Structure button and preview panel in the Peptide, RNA/DNA, and Chem/Blob tabs. Structures can be pasted from common formats (cdxml, cdx, SMILES, molV2000/3000, InChI) and searched as substructure, similar, full, exact, or full including tautomers, with results returned directly in the monomer panel. Structure and text filters can be combined to refine monomer results within the active library.
Highlight coloring is now available
You can now highlight atoms, labels, and bonds to draw attention to specific parts of a chemical structure to facilitate clear communication and focused presentations. This feature is available in the Colors section of the Properties panel or as a tool in the right-hand context toolbar. Choose a highlight color from the predefined palette or enter an exact hex code to create publication-ready chemical drawings.
Notebook descriptions are now viewable in the application
Notebook descriptions are now displayed in ChemDraw+ in both the Notebook List and Notebook Details views.
Import & Export options have expanded
ChemDraw+ now supports importing MOL and RXN files. When these files are brought into the application, they are automatically converted to CDXML format, enabling full editing capabilities within ChemDraw+. Additionally, export options in ChemDraw+ have expanded to include expanded MOL and SD files (V3000) as well as RXN files.
