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 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.

For Linux you have to install R and Rserve (see Rserve installation below!).

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

Bio7 Documentation

For more information about Bio7 please consult the soon updated Bio7 User Guide.

A plethora of Bio7 videotutorials for an introduction can be found on YouTube.


Apropos: On MacOSX you can change the default font settings of, e.g., the file “Navigator” on Bio7 (and Eclipse in general) with the TinkerTool:

Increase the System font (tab Fonts) to 14pt and it will look very nice on MacOSX with the default custom Bio7 css themes which also uses 14pt fonts.

In addition the ImageJ Awt/Swing fonts can be increased or decreased with the Preferences (restart required):

Preferences Bio7->Preferences ImageJ->Fontsize correction


I created an update for MacOSX and Windows which can be easily installed with the Update Manager of Bio7. This update fixes some bugs (native process pid interrupt which affects Windows and MacOSX only), adds two new scripts (helper scripts to arrange data for classification) 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 potentially their preferences will be updated.


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

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

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

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