As a recent change in the ChemAxon - SciTegic collaboration, ChemAxon took over the responsibility for developing the ChemAxon Pipeline Pilot component collection with continued active support from our partner. A new, improved collection package has been released since then by ChemAxon in March 2008. The presentation covers the new components, improvements of existing components and plans for future development.
Free download of component collection is here: http://www.chemaxon.com/integration/download.html

Transcript

  • 1. Pipelining ChemAxon Szilard Dorant Solutions for Cheminformatics
  • 2. ChemAxon and Pipeline Pilot - What’s new ChemAxon took over the responsibility of maintaining and supporting the ChemAxon Pipeline Pilot Component Collection with the continued active help from SciTegic. • New components for current ChemAxon functionality • Support for new ChemAxon functionality more quickly • Support from ChemAxon directly ChemAxon released component collection version 1.2 in March 2008
  • 3. The Component Collection: Quick facts • Free of charge • Open source : Java sources are also included • Available from ChemAxon or SciTegic • Latest version : 1.3 – Released in July 2008 – Requires JChem 3.2 / Marvin 4.1.2 or better – Tested against Pipeline Pilot 6.1.1
  • 4. Available functionality • Standardizer • Chemical Terms expressions for filtering and calculations (including logP, logD, pKa, HBD, HBA, Isoelectric point, PSA and more) • Reactor • JChem chemical database: insertion, search and retrieval of structures; create and drop structure tables • Marvin sketcher and viewer (structure editing and display) • Major microspecies (major protonation form) • Microspecies distribution • Burden eigenvalue descriptor (BCUT)
  • 5. Molecular Table Viewer
  • 6. Calculator
  • 7. Chemical Terms Calculator • Use arbitrary Chemical Terms New in 1.3 expressions • Results stored to arbitrary properties • Up to 10 expressions can be calculated in a single component for maximum efficiency
  • 8. Chemical Terms Filter
  • 9. Canonicalization with Standardizer Upgraded in 1.2 Simple to use, but now full complexity is also available: • Simple actions (checkboxes) • Configuration string (simple or XML) • Configuration file
  • 10. Database Connection • Provides a convenient way to define a JDBC connection parameter set within a protocol • Other ChemAxon components refer to this parameter set by a symbolic name (e.g. “myConnection”) • Multiple instances may be used in a protocol if needed • Each component creates its own JDBC connection to the database according to these parameters
  • 11. JChem Base Insert New features: Upgraded in 1.2 • Duplicate filtering option (using Pass and Fail ports) • Returns cd_id (primary key) values • Two input modes: – read structure source from a specified property – if property not specified uses PP input molecule • Insert into additional data fields* *Under development, as of version 1.3 limited to string database column types
  • 12. JChem Database Search Upgraded in 1.2 • Several search options were added • Easier protocol integration and better performance due to concentrated functionality
  • 13. JChem Base demo protocol New in 1.2
  • 14. Reactor Features: • Reaction scheme can be specified as file or string (reaction SMARTS) • Sequential or combinatorial mode • Product or reaction output • Select products to include • Inserts product number and reaction number into specified tags • Four tagger components available to distinguish inputs of multi- reactant reactions New in 1.2
  • 15. Combinatorial Reactor Example New in 1.2
  • 16. Improved error reporting New in 1.3 • Helps to track down problems quicker • More information is displayed in the error dialog: Marvin / JChem version, the current structure, etc. • If the environment variable CHEMAXON_PP_LOG_DIR is set, an even more detailed error report will be appended to the file quot;pp_error.txtquot; in the specified directory
  • 17. The “Java (On Server)” Component • Most members of the ChemAxon collection are based on this generic PP component • A single “Component” interface with three methods to implement: – onInitialize(): initialize once – onProcess(): runs for each input or each output – onFinalize(): cleanup • Java API provided for accessing – component parameters and the data records – SciTegic Molecule objects (Molecular Toolkit)
  • 18. ChemicalTermsFilter OnInitialize()
  • 19. ChemicalTermsFilter OnProcess()
  • 20. Planned components • JChem Cartridge for Oracle • Instant JChem end user desktop cheminformatics solution • Name to structure conversion • Tautomer and conformer generation • Conversion of various structure file formats • MCS based clustering Node release cycle is fast and flexible. Please advise us on priority and additional functionality for future node development.
