Bio7 can be extended with R packages, Eclipse plugins and ImageJ plugins. Another very easy option to extend the Bio7 Graphical User Interface with R actions are dynamic menus which can be used, e.g., for personalized workflows or repeating tasks. The provision of new menus and nested menus is simple and can be arranged for different tasks.
Three different menu locations can be populated with custom scripts. One location is the context menu of the R-Shell view.
To extend the R-Shell context menu scripts have to be copied to a default script location of the Bio7 installation. Folders in the locations constitute a new submenu, nested folders results in nested submenus. It is not necessary to restart the application because the menus are updated automatically and copied scripts are instantly available as an executable action
Executable R scripts in a menu can be used for instance to offer different plot actions (there is a special hidden vector variable available ‘.r_shell_vars‘ to get multiple selected objects, e.g., to plot a selected variable (without the need to use a Java to R API!):
plot(get(.r_shell_vars[[1]]))
In addition the different default script locations can be changed in the preferences. This is handy if you want to share scripts in a team using, e.g., GIT for updates and reproducibility. For Bio7 you can install the Eclipse GIT plugin (Menu: Help->Install New Software, Select ‘Eclipse Repository’, search for ‘git’, select and install ‘Git integration for Eclipse’) to share a local script folder on GitLab, Github, Bitbucket, etc.
A short overview how to create custom menus in the R-Shell context menu is demonstrated in the video below:
Please note that the menus can also be extended with JVM script types which run on the JVM (Java, Jython, Groovy, BeanShell, JavaScript, ImageJ Macro). If a custom interface should be created a selected JVM language can be used to create custom views and populate a special custom perspective. Special API functions for the interaction of Java and R are available, too.
An example how to build and invoke a custom interface with Java SWT is shown in the video below (a pure Java example installing and using the WindowBuilder plugin):
A new release of Bio7 is available which is built upon Eclipse 4.11 and the latest Java OpenJDK. This new version comes bundled with OpenJDK 12, supports the dynamic compilation of Java 11 and fixes several annoying bugs on MacOSX (e.g., shutdown crashes).
The R interface has been improved and the R-Shell now updates the workspace display automatically after a R code evaluation or R data transfer.
In additon for Bio7 3.0 the themes have been improved (especially for MacOSX and the Mojave dark mode) and some Touch Bar actions for MacOSX are available, too (if the MacOSX device has a Touch Bar).

Huge amount of changes since the last release. For all changes, see:
Just download the *.zip distribution file from https://bio7.org and unzip it in your preferred location. Bio7 comes bundled with a Java Runtime Environment, R and Rserve distribution and works out of the box.
Linux:
Download and extract the installation file from https://bio7.org. For Linux you have to install R and Rserve (see Rserve installation below!).
MacOSX:
Download and extract the installation file from https://bio7.org.
If you start Bio7 a warning or error can occur because of the changes how Apple treats signatures! To allow Bio7 to start see this instructions for Yosemite, Sierra and Mojave:
In addition for MacOSX you have to install R and Rserve (see below!).
Linux and MacOSX Rserve (compiled for cooperative mode) installation:
To install Rserve open the R shell and then execute the menu action “Options -> Install Rserve (coop. mode) for R …” for different R versions. This will download an install Rserve in your default R library location, see video below (please make sure that your default Linux R library install location has writing permissions!). In cooperative mode only one connection at a time is allowed (which we want for this Desktop appl.) and all subsequent connections share the same namespace (default on Windows)!
Recently I discovered the package PyRserve for Python which connects Python with R using Rserve.
This is extremly useful because Bio7 already integrates Rserve and has special GUI interfaces available to transfer, e.g., data from spreadsheets, ImageJ image and selection data (also georeferenced), Java simulation data, etc.
With this new Rserve connection this data can now easily transferred from Java and R to a Python workflow.
Python as a language is already supported in Bio7 with an integration of Jython (which runs on the Java platform a supported JVM language like Groovy, JavaScript, Scala, etc. and has a direct access to the Bio7 API).
In additon native Python can be executed with the default Bio7 Python editor if configured in the native preferences of Bio7 (running as an external process in a Bio7 Python shell if enabled).
However since Bio7 is based on Eclipse a more powerful editor for Python/Jython can be installed with PyDev which is a complete Python IDE for Eclipse and available as an Eclipse plugin which can be installed with the Bio7 (Eclipse) Update Manager
If PyDev is installed you can create Python projects in Bio7 and execute Python and Jython scripts depending on the settings in it’s own process (e.g. with the action editor context menu-> Run As->Python Run) .
In addition it is possible to use a special Bio7 toolbar action (visible if the PyDev editor or Bio7 Python editor is opened) to interpret the content of the PyDev editor in the current Bio7 Jython or Python process (which is of no importance for the following use of PyRserve!).
PyRserve can be installed easily using the pip command in the python shell:
However since the Bio7 functionality can be easily extended with scripts (which can be added dynamically to a menu copying them to a special scripts location, see screenshot below) I decided to write two short Groovy scripts to start and stop Rserve not controlled by the Bio7 Java connection interface (and if necessary disconnect R from a current Bio7 controlled Java connection).
The ‘Start_PyRserve’ script starts R and Rserve if not alive in the Bio7 R console and also disconnects from a running Java Rserve connection if activated.
Note that in Bio7 only one connection to Rserve is allowed (Rserve cooperative mode).
The ‘Stop_PyRserve’ script reconnects Python (closed in the Python scripts!) to shutdown Rserve and returns to the Bio7 console and R (Pydev has it’s own console).
This shutdown command is excecuted by an external Python process. To get the path for the Python interpreter we also have to set the Bio7 Python path (not PyDev!) in the Bio7 preferences (see Windows screenshot below – normally not necessary on Linux or when the Python interpreter is on the OS PATH!).
With this two scripts it is now (more secure) possible to start Rserve and use the Bio7 Java interface, e.g., to transfer image data to R (ImageJ to R), start the Python connection (which disconnects Java) and use the image data inside a Python workflow (see the second example).
Here a first example script to transfer random numbers (in PyDev use the context menu action ‘Runs As->Python Run’ of the editor to execute the Python script) with a PyRserve connection.
import pyRserve import matplotlib.pylab as pltconn = pyRserve.connect()matrix = conn.eval("tryCatch({matrix<-imageMatrix}, error = function(e) {return ('NULL')})")conn.close()if matrix != 'NULL': # we have to transpose the image for a correct view! matrix = matrix.T plt.imshow(matrix) plt.colorbar() plt.show()
Here a summary of the installation and configuration steps necessary for Bio7 to use PyRserve and execute Python scripts with the powerful PyDev editor:
Install the PyDev editor and configure the Python path
Install PyRserve (pip install PyRserve)
Configure the Python path of Bio7 (Preferences Bio7->Preferences Native)
Install the Groovy Start/Stop scripts for PyRserve (simply unzip Examples_PyRserve.zip in one scripts location – Open ‘Scripts->General->Open_Script_Location’ from the main Bio7 menu or in the context menu of the R-Shell view open General->Open_Script_Location’. Put them in an extra folder for a submenu!
Start the ‘Start_PyRserve’ script to start Rserve (not Bio7 controlled!)
Execute a Python script which connects and disconnects PyRserve
Stop the server and shutdown Rserve with the ‘Stop_PyRserve’ script
A new release of Bio7 is available. The new Bio7 2.9 release comes with a plethora of new R features and bugfixes.

In Bio7 R and Java code can be easily combined in the Bio7 platform. For instance to create Graphical User Interfaces in Java (with SWT or JavaFX), transfer image pixel/selection data from ImageJ and finally doing the analysis parts in R code/scripts which can be called from within Java (an easy to use API on top of Rserve in Bio7 is available, see, e.g., Groovy examples here).
However sometimes it is necessary to debug the Java language as part of such combined work. In Bio7 (based on Eclipse RCP) the very powerful Java debugging tools from Eclipse are available by default.
In addition in Bio7 it is possible to debug dynamically compiled Java classes in the same Bio7 process (using Java like a scripting language is a special feature of Bio7).
The video at the bottom of this page demonstrates the use of a remote debugging connection on the same computer (localhost connection) to debug dynamically compiled/executed Java code.
Debugging a Java process which has already started (Bio7 in this case) is only possible if Bio7 is started beforehand with the following Java arguments inside a shell to start a debug server connection:
Windows (started from the current directory = Bio7 installation directory): Bio7.exe -vmargs -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
Mac (given the full path to the Bio7 executable): /Applications/Bio7.app/Contents/MacOS/Bio7 -vmargs -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
Linux (started from the current directory = Bio7 installation directory): ./Bio7 -vmargs -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
Furthermore the compiler debug information option has to be enabled in the Bio7 Java preferences (for the dynamic compilation process) and a seperate debug connection has to be started for this Java class (with the available Eclipse debug configuration dialog).
In the video below I (hopefully) demonstrate how you can (graphically) debug a simple cellular automata simulation like the Game of Life within a running Bio7 (Java) process.
