Bio7 GUI

  • Improved the startup layout for Bio7. The application now starts maximized.
  • Increased the Bio7 splashscreen.


  • Updated the embedded Java Runtime Environment to 1.8.45.
  • Updated the integrated JavaFX SceneBuilderKit.

  • The ‘close’ method is called automatically if a custom view is closed.


  • Added and fixed some examples for Bio7


The installation of Bio7 is similar to the installation of the Eclipse environment. Simply decompress the downloaded *.zip file in a preferred location on your file system. After decompressing with a standard zip-tool (like WinZip, Win Rar) the typical file structure of an Eclipse based application will be created. To start the application simply double click on the Bio7.exe file.

Knitr with Bio7


In Bio7 it is possible to write a documentation in knitr. A simple visual and textual HTML editor (based on JavaFX) and an embedded Latex editor (based on TeXclipse) helps in the creation of a *.html or *.pdf documentation. For the *.pdf creation a TeX environment has to be available (Windows e.g. MiKTeX).

Overview video:

Note that there is still a bug in the visual JavaFX HTML editor (JavaFX SWT bug) to select text in the visual part of the editor. A workaround is to use the combination of Shift- or Ctrl-key and a mouse-click.

In upcoming releases more improvements for R reports will be available in Bio7.

Solving CentOS 7, Fedora Problems at Startup Wrong Layouts


Here I describe some notable Linux distribution errors which can be corrected with the following startup options (1) and CSS changes (2).

1. Startup Problems

There seems to be problems with CentOS 7  in general. If the application does not start correctly, e.g., the Bio7 window will not be shown then add the following arg (e.g., with a text editor) to the Bio7.ini file in the Bio7 base folder (installation folder).


This arg had to be added like this in the*.ini file (see screenshot – don’t place it wrong else an error will occur!):


After saving the file Bio7 should be started on CentOS 7 (see screenshot below)! Please note that you can also adjust the Java memory there.


Another rare error occuring in Fedora is described here!.
However I tested Bio7 on the latest Fedora release and Bio7 started without any problems.

2. Layout Problems

If the layout of your distribution seems to be distorted (e.g., maximize buttons are to small – could be occuring in the default layout of Fedora and CentOS!) this can be corrected in the Bio7 CSS. The file can be found under:

(win7.css was reused for Linux so please don’t wonder)

The following changed css attributes will correct the height of the toolbars (changed attributes in bold):

.MPartStack {
color: ‘#org-eclipse-ui-workbench-INACTIVE_TAB_TEXT_COLOR';
 swt-tab-height: 36.0px;

} {
swt-shadow-visible: false;
 swt-tab-height: 36.0px;

/*Important to set height for the view menus!*/
CTabFolder {
swt-corner-radius: 15.0;
swt-tab-height: 36.0px;

Of course you can change other attributes as well, e.g.,  if you want to change a color.
