Update 2 (version 2.5.5) - Details

This update includes enhancements and corrections to Discovery Studio 2.5.

  • Discovery Studio has been upgraded to work with the 64 bit version of the Pipeline Pilot 7.5 server. This simplifies the installation process, as you no longer need to maintain both 32 and 64 bit versions, and helps you to improve performance of processor heavy calculations by allowing you to run them on 64 bit servers.
  • MODELER is upgraded to version 9v7, and includes native 64 bit version of the package. In addition, the new version complies with the latest PDB format for DNA/RNA, ligands, and ions (now reads and writes metal ions correctly).
  • CHARMm has been upgraded to version 35b1, and includes a native 64 bit version of the package.
  • New protocols are available: Filter by Property and RCSB Structure Search in General Purpose and
    Create 3D QSAR Model in QSAR.
  • The Dock Ligands (GOLD) protocol has been modified to support version 4.1 of GOLD.
  • New Discovery Guides have been added: Dock Ligands and Sketch and Align Molecules.
  • A new tool panel has been added: Superimpose Proteins.
  • New tools and enhancements have been made for Analyze Binding Site, Analyze Protein Conservation Pattern, Build and Edit Nucleic Acid, and Build and Edit Protein tool panels.
  • Tooltips are enhanced with improved information and links to detailed help.
  • New options and enhancements are available in the Molecule Window and Sequence Window.
  • Scripting includes new methods for accessing plots and dendrogram views, creation of pi-interaction and rotatable bond monitors, and saving images from the Graphics View.

Additional enhancements and bug fixes have been made for details, see "What's new in Discovery Studio 2.5.5" (available from the readme on the distribution before installing, or the product help after installation).
