Bellview

This application has been designed as a tool to simplify the process for performing Bhattacharya analysis on large data sets for the indirect determination of reference intervals.

Version 2 has been substantially rewritten primarily to gain familiarity javafx for the graphical user interface. However, the ability to import age and gender has been added so that partitioning can be done within the application rather than forcing the user to do this prior to importing data.

Installation

Application installer packages are available for Windows and Linux (bellview-x.x.x-win.exe and bellview-x.x.x-linux_amd64.deb respectively)

These packages include a JRE image and should run out of the box once installation is complete.

The zip binary Bellview-x.x.x-bin.zip can be run on any platform but requires a Java Runtime Environment (JRE) or Java Development Kit JDK (Version 17 or later) and JavaFX installed. Startup scripts can be found in the bin directory but you will need to set the JAVA_HOME environment variable to the location of your JDK or JRE first.

Suitable JREs or JDKs are available from https://adoptium.net/ or https://www.azul.com/

JavaFX SDKs are available from https://gluonhq.com/products/javafx/ alternatively, Azul has JRE or JDK packages that include JavaFX (JRE FX, and JDK FX). At the time of writing these could be downloaded from https://www.azul.com/downloads/?package=jdk#zulu but make sure you scroll down the page a bit and select the correct package and version (17 or later)

Windows

Search for the option to edit environment variables for your account. Alternatively, from the Control Panel -> System and Security -> System -> Advanced system settings -> Environment Variables

Create a new entry with variable name JAVA_HOME, and variable value the path to your JDK or JRE (typically something like \Program Files\Java\zulu17.40.19-ca-fx-jre17.0.6-win_x64)

Alternatively JAVA_HOME can be set directly in the startup script. See line 20 of app.bat, remove the @rem statement, and update the path as necessary.

The application can then be started with:

bin/app.bat

Linux or Mac

The JAVA_HOME environment variable can be configured in the usual way for your shell such as .bashrc or .zshrc

Alternatively JAVA_HOME can be set directly startup script. See line 70 of bin/app, uncomment the line and update the path as needed. On Debian based systems this will be typically JAVA_HOME="/usr/lib/jvm/zulu-fx-17-amd64"

Ensure permissions have been updated so that the startup script can be executed, then start with:

bin/app

Source

The source files are available from https://github.com/dche658/bellview.

At the GitHub repository, if you click on the green "<> Code" button you should see a link to "Download ZIP". Download and then extract the bellview-master.zip archive.

Open a terminal window and change to the bellview-master directory.

To build a platform specific installer, run the command

gradlew jpackage

Hopefully, this will download all the necessary dependencies and create the installer package in /bellview/app/build/jpackage

Alternatively to build a runtime image execute

    gradlew runtime
