BKChem Description

Chemical drawing program written in Python BKChem is a free chemical drawing tool developed in Python, an interpreted and very nice programming language. This implies some of the program features:· platform independence - BKChem should run on any platform that Python does.· performance - as Python is interpreted language you should not expect the performance of a native code compiled application (in present days a very cheap tradeoff for platform independence). However BKChem should be pretty usable on all modern systems. Here are some key features of "BKChem": Drawing: · bond-by-bond drawing · bond lenght and angle restrictions to assist with the drawing · ready to use templates of common rings · ability to expand common groups from abbreviated to structural form · Support for linear formulas (such as -CH2CH(COOCH3)2) · radicals, charges... · arrows (several types - normal, retro, equilibrium, etc.) · rich text · color support · simple vector graphics (rectangles, circles, polygons etc.) Editing: · unlimited undo and redo capabilities · aligning · scaling · rotation (2D, 3D) · aligning of molecules so that particular bond is horizontal/vertical · rotation of molecular fragments around bonds (conformation changes) · definition of personal preferred drawing style (bond lenghts, widths, colors...) Export: · full export to SVG (native data are transparently embedded into SVG file) · full export to OpenOffice Draw format · full export to ODF (OpenOffice 2.0) format · full export to Encapsulated PostScript · full export to PDF · full export to PNG (if pycairo is installed, available in Windows binary build) · basic support for both CML1 and CML2 · Molfiles · generation of SMILES Import: · basic support for both CML1 and CML2 · Molfiles · SMILES (subset) · INChI (subset) Other features: · localization support (currently English, French, Czech, Polish, German and Traditional Chinese translations are available) · native format is XML based · validity checking of drawn structures · support for user written plugins · support for user written batch scripts · searching for BKChem files containing specified molecules or molecule fragment
