Sketch molecules– isotopes, charges, radicals, lone pairs– stereo atoms and bonds (R/S, E/Z)– diastereomers (ABS/AND/OR)– alias, pseudo atoms– templates– abbreviated and multiple groups– link nodes– curved arrows– attached data– reactions (automapping)

Design queries– generic atoms and bonds– atom lists and not lists– SMARTS expressions (even recursive)– R-groups

View compound sets– Table layout– 3D models

Compatible– MOL, SDF, RXN, RDF (V2000/V3000)– SMILES, SMARTS/SMIRKS (recursive

too)– MRV, CML, PDB– copy/paste

Flexible– 2D Cleaning– 3D geometry/conformers– Shapes, text boxes– Calculation Plugins

Available– Java applets, signed applets– Applications, deployment with

• Installer• Java Web Start

– JavaBeans– Java 1.1-1.5 platforms (Windows, Mac,

Calculator Plugins

• ChemAxon’s plugin loading mechanism enables Marvin to provide access to a wide range of dynamically loaded calculation tools

• A set of plugins is provided by ChemAxon: pKa, logP, logD, Huckel Analysis, Hydrogen Bond Donor / Acceptor, etc.

• Users can easily add their own calculator plugins to this framework

Marvin Applets

Browser-independent solution for integrating Marvin applets into the HTML source:

<script LANGUAGE="JavaScript1.1" SRC="../../marvin.js"></script>

<script LANGUAGE="JavaScript1.1">

<!–

msketch_begin("../..", 460, 380); // arguments: CODEBASE, WIDTH, HEIGHT

msketch_param(“mol", “../structures/benzene.mol”); // structure URL as applet parameter

// alternatively the structure source can also be specified:

msketch_param(“mol", “c1ccccc1”); // structure source as applet parameter

msketch_param(“colorScheme", “cpk”); // applet parameter

…

msketch_end();

//-->

</script>

Applet specific features (1)

1. Both Swing and AWT versions are available for maximum compatibility, the appropriate version for the browser / JRE is automatically selected

2. Signed (trusted)applets enable access to local files, system clipboard and allow printing

3. Modularity– Modular loading of packages ensures fast download-time

– Modules are not included into the main jar, they are loaded on demand

– Preloading of frequently used modules can be specified with applet parameter:

msketch_param("preload", "MolExport,Parity,SmilesExport,Clean2D,MyformatExport");

Applet – JavaScript communication

• The applet API is accessible from JavaScript, providing a convenient solution to– Fetch the current structure from the applet in a

specified file format. This is typically used for sending the structure to the server for further processing.

– Change the structure or display options of the applet without reloading the page.

Marvin Beans

• Use Marvin Beans to add MarvinSketch or MarvinView as a graphical component to your standalone application

• Additional API is accessible for– Import / Export– Performing calculations with plugins– 2D and 3D cleaning of structures– etc.

API example : integration

www.chemaxon.com/marvin/examples/dialog/DialogLauncher.java.txt

JDialog dialog = new JDialog(…);MSketchPane sketcher = new MSketchPane(); dialog.getContentPane().add(sketcher); …Molecule mol= sketcher.getMol(); //getting the sketched molecule

Adding a Marvin Sketch component to a dialog:

Adding a Marvin View component to a dialog:JDialog dialog = new JDialog(…);MViewPane viewer = new MViewPane();Molecule mol = …;viewer.setM(0, mol); //setting a molecule to displaydialog.getContentPane().add(viewer);
