  5. Opening Files Use file menu Drag from explorer JAS3 – Current Status and Prospects, V. Serbo

  6. Plot Manipulation and Printing Or copy/paste into Word, PowerPoint etc. Can send individual plots or full page direct to printer Or save as PS, EPS, PDF, SWF, SVG, PNG, GIF… JAS3 – Current Status and Prospects, V. Serbo

  7. Java Editor, Compiler and Loader Tree shows loaded programs Built-in editor for writing analysis code JAS3 allows any Java program to be loaded. This example “main routine” is taken directly from the AIDA manual Built-in Java compiler JAS3 – Current Status and Prospects, V. Serbo

  8. Miscellaneous Features Save/Restore configuration User Preferences Plugin Manager JAS3 – Current Status and Prospects, V. Serbo

  9. JAS3 Spreadsheet • Simple spreadsheet plugin • for • Displaying results • Calculations • Simple Plots • Supports reading/writing • .csv files • Excel files • Cut/Paste with Excel etc • Coming Soon… • Scripting interface • GUI for building plots • User defined functions • Java, scripting JAS3 – Current Status and Prospects, V. Serbo

  10. JAS3 Scripting • JAS3 has multi-language OO scripting support • Command line, Console, Editor • Major components (e.g. AIDA) have scripting interfaces • Currently have plugins to support • Pnuts – syntax almost identical to Java, fast, well documented and feature complete • Python • Use Jython (the Java implementation of Python) • Limitation: can not call Python libraries written in C • More scripting languages can be added • not restricted to Java implementations (e.g. could use C-Python, JPE) JAS3 – Current Status and Prospects, V. Serbo

  11. Pnuts Language • Currently support Pnuts scripting language • Complete and well documented • http://javacenter.sun.co.jp/pnuts/doc/guide.html • Fast (although not as fast as compiled Java) • Syntax very similar to Java; can compile script into Java bytecode or convert it to Java code • Can easily call compiled Java classes from scripts – best of both worlds JAS3 – Current Status and Prospects, V. Serbo

  12. JAS3 Scripting II Can also write and run scripts Console allows direct interaction with scripting language JAS3 – Current Status and Prospects, V. Serbo

  13. AIDA - Abstract Interfaces for Data Analysis • AIDA is a standard set of interfaces for creating and manipulating histograms, n-tuples and related data analysis objects, like Plotter, Fitter, etc. • AIDA defines storage XML format. • It has been created cooperatively by a group of developers working on high-energy physics data analysis tools. The goal of the AIDA project is to provide the user with a powerful set of interfaces which can be used regardless of which analysis tool they are using. • Only define “protocol” for analysis objects, no internal details • AIDA defines behavior, analysis tool provides implementation • C++ and Java versions of interfaces are generated from the AID files. JAS3 – Current Status and Prospects, V. Serbo

  14. AIDA Examples • IHistogram1D • IAxis axis() • void fill(double x) • void fill(double x, double w) • double mean() • double rms() • double binEntries(int index) • double binError(int index) • …. • For more details on AIDA, see: http://aida.freehep.org • IAxis • int bins() • double lowerEdge() • double upperEdge() • double binLowerEdge(int index) • double binUpperEdge(int index) • double binWidth(int index) • int coordinateToIndex(double x) • …. JAS3 – Current Status and Prospects, V. Serbo

  15. JAIDA • JAIDA = Java implementation of AIDA • Complete implementation of AIDA interfaces • With a few exceptions • Support for plot styles is somewhat limited • Some missing features in ITree, like cp, mv • Uses Java “service provider mechanism” for dynamic loading of services at Runtime • Can be used to add support for new fitters, stores etc. • Have defined “developer level” interfaces for IOptimizer, IStore etc • Uses Java Expression Library (JEL) for runtime compilation of expressions (for tuple evaluators and functions) JAS3 – Current Status and Prospects, V. Serbo

  16. JAIDA – Features continued… • Fitting • support for multiple fitting engines (optimizers) • UNCMIN (pure Java) • Minuit (needs minuitAdapter native library) • Support for multiple fitting methods • LeastSquares, Chi2, BinnedMaximumLikelihood and UnbinnedMaximumLikelihood • Stores • Read/Write support for AIDA XML format (with built-in gzip) • Read support for HBOOK/PAW files (needs hbookAdapter native library) • Read support for Root files (write support hopefully coming soon) • Future plans to add: • SQL interface, binary store format, text file support … • Plotting • Two implementations of IAnalysisFactory • BatchAnalysisFactory – dummy plotter, ignore calls to IPlotter • AnalysisFactory – Full plotter functionality • Multi-Threaded – plots update in real-time as they are filled • No need to call interact() or refresh() • Support for embedding plotter • In other Java GUI’s • In Java servlets for web based applications. • Graphics export in many formats including: • PDF, EPS, SVG, SWF, PNG, GIF, JPG JAS3 – Current Status and Prospects, V. Serbo

  17. C++ program AIDA- JNI AIDA AIDA AIDA-JNI • C++ interface uses AIDA-JNI JAIDA (Java) • AIDA-JNI partially generated by AID, partly by hand • Does support full AIDA functionality JAS3 – Current Status and Prospects, V. Serbo

  18. Using JAIDA with Java JAS3 – Current Status and Prospects, V. Serbo

  19. Using JAIDA with Python JAS3 – Current Status and Prospects, V. Serbo

  21. Future Plans for JAIDA • Complete implementation of missing features • Continue to track improvements to AIDA standard • Add support for function arithmetic • Web Interface • Support for “Remote AIDA” • Support for more storage formats • Need good binary IO format .. either AIDA standard or roll our own • Future AIDA developers’ meetings JAS3 – Current Status and Prospects, V. Serbo

  22. JAS3 and AIDA • JAS3 uses JAIDA - supports all AIDA functionality, including • Histograms (includes arithmetic, projections, etc.) • Clouds (unbinned histograms, scatterplots) • Plotter • Tuples • Fitting – AIDA interfaces allow for multiple fitters • Uncmin -- pure java minimizer • Minuit -- Fortran called by Java Native Interface (JNI) • IO • AIDA XML, PAW, Root • JAS3 supports user interaction with AIDA in three ways • Scripting (Pnuts, Python etc) • Compiled (Java) code • GUI – Plotting, Fitting, Cuts etc. JAS3 – Current Status and Prospects, V. Serbo

  23. Graphical Interface to AIDA Histograms, Clouds, Tuples all presented in AIDA tree .aida files, .hbook files, .root files all presented as AIDA objects Drag items onto page, or use (popup) menus JAS3 – Current Status and Prospects, V. Serbo

  24. Tuple Explorer - Plots Histogram Profile Works with any tuple, read from file or dynamically created ScatterPlot XY Data (More appropriate for smaller data sets) JAS3 – Current Status and Prospects, V. Serbo

  25. Tuple Explorer – Define Columns JAS3 – Current Status and Prospects, V. Serbo

  26. Tuple Explorer - Cuts JAS3 – Current Status and Prospects, V. Serbo

  27. Tuple Explorer - Tabulate JAS3 – Current Status and Prospects, V. Serbo

  28. Tuple Explorer – Record Source To be used with record loop JAS3 – Current Status and Prospects, V. Serbo

  29. Record Sources Opening record (or event) based files causes the run control toolbar to appear Supports random access and “tagged” data sets (mainly for event displays) JAS3 – Current Status and Prospects, V. Serbo

  30. JAS3 Plugins • JAS3 is based on the Freehep Application Framework, which provides a basic application framework into which extension modules, or "plugins" can be loaded. • The application framework provides general purpose functionality, such as top level GUI (windows, menus etc.), help system, storing and retrieving user preferences etc. • All of the data analysis specific functionality of JAS3 is provided by a set of extension modules. • Modules communicate with each other via service interfaces and notification events. JAS3 comes with a standard set of service interfaces and notification events, but new plugins can also define their own interfaces and events. JAS3 – Current Status and Prospects, V. Serbo

  31. JAS3 Plugin II • Plugin functionality: • Do some plugin-specific task • Use services provided by other plugins • Provide services to other plugins • Modify JAS3 menus and pop-up menus • “Core” Plugins – provide basic services • Simple: File Opener, Memory Status, Status Bar, … • More Complex: Web Browser, Plotter, Console, XMLIO, … • “Extensions” – separate packages • Included with JAS3 distribution • AIDA, TupleExplorer, JAVA Compiler and Editor, Spreadsheet, … • Specific to particular Experiment • BaBar Ambient DB Browser: AmbientPlugin, Geant4 Plugin, etc. • Partial Tutorial on writing a plugin: http://jas.freehep.org/jas3/developers/tutorial.jsp JAS3 – Current Status and Prospects, V. Serbo
