iBabel gives access to chemical file conversion, sub-structure searching, overlays, sorting and manipulation of lists of compounds, also include structure viewing capabilities, using JMOLand JChempaint. Provides a GUI to ChemSpotlight allowing searching your hard drive for chemical content.
For the 2.6 release of of iBabel, the major aim of the new version was to provide access to the new command-line tools that are available in Open Babel 2.2.0. To access the tools you will need to download the latest version of Open Babel from here.
If you want to use the Chemdraw plugin or Marvin as the molecule viewer/editor you will need to download them also. The increasing number of tools has meant I've had to rethink the User Interface for the "Tool" tab, and I'm particularly grateful for the input from Alex Griekspoor and Philip Buckley. The way I've set up the interface is the input that is common to most tools (input/output files) I've left in the main tab, the input that is unique for each tool appears in the box when the tool is selected from the dropdown menu, as shown for a selection of the tools in the images below. One of the advantages of this arrangement is that as new tools become available via OpenBabel I can add them without having to rethink the interface. I just need to add a menu item to the tools menu and an additional options box that will only be displayed when the menu is selected.
