For those who don’t know Bio7. The application Bio7 is an integrated development environment for ecological modeling, scientific image analysis and statistical analysis.

It also contains a feature complete development environment for R with an advanced R editor, R developer tools and interfaces to perform scientific image analysis with R and the embedded ImageJ application.

New features:


  • Bio7 3.3 is based on Eclipse 4.19
  • AdoptJDK updated to Java version 16
  • JavaScript bundled with AdoptJDK (Nashorn)
  • Updated JavaFX libraries (version 16) bundled with AdoptJDK
  • Bundled with R 4.0.5 (Windows only!)
  • Updated Java libraries (Groovy, JavaScript, etc.)
  • Added some Eclipse default themes (e.g. “System” theme for Linux)
  • Improved the themes, wording and some visuals
  • Improved the Bio7 file wizard in the toolbar
  • Added a sort and collapse actions to some editors outline view


  • New “Attached Packages” view which displays datasets and function of packages. Datasets can directly be loaded

  • The “Load” and “Save” action in the R-Shell View can now load and save files in different selected formats (the command will be loaded into the textfield of the shell).

  • Updated Rserve to version 1.8.7
  • Created an easy to use Rserve install method action (R-Shell view->Context menu->Rserve->Install Rserve)


  • Added dynamic compilation support for Java 15 (support for “Raw String Literals” to avoid the “quoting hell” of embedded commands in strings)
  • Added a new Java interface API method to execute R code from Java in a job with plotting and intermediate plotting support


  • Updated Groovy interpreter
  • Groovy editor now supports “Raw String Literals”


  • Bundled a Nashorn JavaScript engine with AdoptJDK 16
  • Added an interpret toolbar action when the Eclipse GenericEditor is installed and a JavaScript file is opened with the editor


  • Updated the ImageJ plugin to version 1.53j18
  • Huge improvements since the last Bio7 release (this plugin can be continuously updated within Bio7), see release notes:
  • Improved the close method for all plugins
  • Detached views can now be closed by name in a macro, etc.
  • Selected Composite Image channels are now displayed colored in the status line of Bio7
  • Added the latest ImageJ macro templates

R & ImageJ

  • Improved the image classification plugin (bundled with the application) and visuals
  • Classified images can now be post-processed with an ImageJ macro for object recognition or particle counting, etc.

Download and Installation:


Just download the *.zip distribution file from and unzip it in your preferred location. Bio7 comes bundled with Java AdoptJDK, R, Rserve and works out of the box.

Note for the Rserve installation:

The install action installs  a special Rserve version compiled for cooperative mode from Github. In cooperative mode only one connection at a time is allowed (which we want for this Desktop apl.) and all subsequent connections share the same namespace (default on Windows)!

MacOSX startup notes:

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, Mojave and Big Sur:

First try to open the app with the context menu to allow the execution. If that won’t work try the following:

Yosemite: Open an app from an unidentified developer
