SketchEl is an interactive chemical molecule sketching tool, and molecular spreadsheet data entry application. The feature set provided by the molecular sketcher is largely limited to the minimum features required to conveniently edit diagram representations of small molecule structures. Toolbars, templates, mouse gestures, keyboard shortcuts, utility commands and several view modes are offered in order to make this as convenient as possible. Molecules can be easily interconverted with the ubiquitous MDL MOL file format, though not not necessarily without information loss. Molecule diagrams are rendered interactively in high quality, and can also be exported as SVG graphics.
The newer datasheet feature of SketchEl allows viewing and editing of simple tables of data, for which each column is a common scalar type (string, int, real, boolean) or a molecule. Editing and viewing of molecules is linked to the molecule sketching tool. The datasheet editing is intended to be convenient for entering numeric property and identification data, alongside the molecular structures of interest. The native format is XML based, with features for interconverting with MDL SD files.
Feature-complete. Version 1.00 provided all of the baseline features for single-molecule sketching. Subsequent improvements include the datasheet editor and SVG export, as well as regular bug fixes and minor improvements. Most recent files often contain experimental features which may not have been tested extensively. Consult changelogs for more information.
No official user documentation exists at the present time, though the menu entries, toolbar icons and popup help should be largely self-explanatory, given a modicum of experimentation. The most uptodate description of the molecule file format is provided on the Molecular Materials Informatics website.
