Updated Eclipse ImageJ Plugin Available


I released a new version of the Eclipse ImageJ plugin based on ImageJ 1.52q44.

  • Updated the ImageJ plugin to version 1.52q44
  • Improved the embedded and detached PlotWindows. Now all plot windows are simultaneously resized according to their parent canvas (embedded or detached – animation below)
  • Fixed a bug in the detach menu action (wrong id and panel settings)
  • Removed the ‘*’ tab icon (usually indicating an unsaved editor file) from the detached custom view by deleting the ‘ISaveablePart2’ interface

Bio7 MacOSX And Windows Update Available


I created an update for MacOSX and Windows which can be easily installed with the Update Manager of Bio7. This update fixes some bugs (which affects Windows and MacOSX only), adds two new scripts in the R-Shell view and updates the ImageJ plugin to version 1.52o33.

Before you update Bio7 make sure that you make a backup of possible installed scripts and ImageJ plugins in the default script and ImageJ plugin location because these two plugins and their preferences will be updated (it might be a good practice to externalize these locations in the Bio7 preferences for updates in the future).


1. Add the update sites below to the Update Manager (Help->Install New Software)

2. Add the URL (Location) of the Update Site (see below).

3. Close the Update Manager and then check for Updates (Help->Check for Updates).

4. Select Bio7 and confirm all licenses and unavailable certificates during installation.

Update Sites for Windows and MacOSX:

Windows: https://bio7.org/update/win/repository
Mac: https://bio7.org/update/mac/repository

Easily Built And Share Custom R Menu Scripts With Bio7


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!):


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):

Bio7 3.0 Released


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:


Download and Installation:


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.


Download and extract the installation file from https://bio7.org.
For Linux you have to install R and Rserve (see Rserve installation below!).


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:

Yosemite: Open an app from an unidentified developer

Sierra: Open an app from an unidentified developer

Moave and Sierra: How to fix “Application” is damaged and can’t be opened error in macOS Mojave and High Sierra.

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)!

Installation of Useful R Packages

R packages which are useful in combination with Bio7 can easily be installed with the R-Shell context menu “Packages” action:

R-Shell context menu->Packages->Install_Default_R_Packages

MacOSX Eclipse Fontsize Correction

To fix the default font size on Eclipse (a matter of taste) I wrote a short summary on the Github page how to fix the font size (see https://github.com/Bio7/EclipseImageJ1Plugin 1 – bottom page).

The plugin source and more information can be found on Github:
