Java Analysis Studio - PR2 January 1998

Release Notes

The most recent version of this document can be found at: http://www-sldnt.slac.stanford.edu/jas/help/pr2/relnotes.html

Java Analysis Studio is an application for High Energy Physics data analysis. It allows analysis of data from a wide range of data sources including PAW ntuples, SQL databases, flat files, hippo files, and (in future releases) ROOT files and Objectivity databases. Java Analysis Studio is a client-server based application, allowing desktop access to data stored anywhere on the internet. The network protocol is optimized to allow rapid access to data even over slow network connections.

Java Analysis Studio provides an easy to use graphical user interface. Users can in addition write analysis modules using the Java Language, using a set of histogramming utilities provided as part of Java Analysis Studio. See the online tutorial for more information on writing analysis modules.

Note: In order to write your own analysis modules, you will need to download the Java Development Kit (JDK) from Sun.  Without the JDK, you will not be able to compile your own files.

To use this pre-release version of Java Analysis Studio you must connect to a data server. We have set up a data server for general trial use at on node sldnt0.slac.stanford.edu. If you interested in setting up your own data server please contact us. Future pre-release versions of the client will allow stand-alone analysis of various types of data (including PAW ntuples, ROOT files and flat text files) without connecting to a server.

This is a pre-release version of the Java Analysis Studio client. It is known to have many bugs and limitations. We are planning to release new pre-release clients every few weeks from now until version 1.0 is available (early summer). We welcome your suggestions for new features.

Known Bugs

General

• This version uses a pre-release version of the Java SWING widgets. These widgets are generally reliable but occasionally show problems due to their pre-release nature.
• Printing does not work in this release of Java Analysis Studio. This is due to a limitation in the current release of swing.

Client

• Connect/disconnect to persistent jobs is not supported.
• When output window is created it always becomes the current window
• Internal help display is very buggy due to swing limitations
• Histogram window does not move to front when double clicking on data

Plotting

• Colors assigned to plots are random
• Suppressed zero on y-axis doesnt work
• Order in which overlayed plots are drawn is random, thus setting filled histogram bars can make data underneath invisible.
