Orbit >= Version 2.53 only works standalone or with Omero 5.3.x. If you want to use Omero 5.2.x, please use the old Orbit version 2.52 or upgrade Omero!

Latest Version 2.67: Bugfix Release

Version 2.65: New cell(-cluster) segmentation, more fluo options, 16bit bugfix, improved tile caching, bioformats 5.5.3
Version 2.55 (Omero 5.3.1): Omero 5.3.1 compatible, Segmentation option to remove tile border objects
Version 2.54 (Omero 5.3.x): Bugfix Release, Fluo image renderingVersion 2.52 (Omero 5.2.x)/ 2.53 (Omero 5.3.x): Multichannel (Fluo) support, Bioformats 5.4.0.
Version 2.52 and 2.53 are identical – 2.52 is for Omero 5.2.x and 2.53 is for Omero 5.3.x. If you just want to open local files without an image server it does not matter which one you use.
Version 2.43: Multi image series support (e.g. VSI files), Bioformats 5.3.0 with support for CZI / JPEG-XR compression.

Recommended Hardware: Quadcore / Hexacore (e.g. I7/I9), 16 GB RAM (or 32 GB if possible).

Before updating an existing installation, please close Orbit at first.

Windows, Linux and Macintosh downloads are for 64bit OS. For 32bit OS (and other platforms) please use the JAR distribution.



For Omero 5.2.x please use the old Orbit version.

Download the orbit_win_xxx.exe and execute it. Follow the installation instructions. Afterwards you should have a desktop icon which you can use to start Orbit.

Hint: Orbit supports high-DPI displays (e.g. 4k monitors) and is able to scale UI elements by itself smoothly. Thus, for high-res displays please right-click the Orbit icon, Properties -> Compatibility and check ‘disable DPI scaling’.

For Zeiss CZI files with JPEG-XR compression Visual Studio 2015 C++ Redistributable is needed.

For Omero 5.2.x please use the old Orbit version.

Download orbit_linux_xxx.tar.gz into a temp folder, extract archive and install the application with the install script:

tar -xzf orbit_linux_xxx.tar.gz
sudo ./install.sh

you should find a shortcut on your desktop and in your main menu (under graphics and education) after installation.

Alternatively: start orbit directly without installing to /opt/orbit and without desktop shortcut:


Hint: This package come with an Oracle JRE. If you want to use your own JRE please be sure to use a 64bit JRE >=1.7. (Tested with Oracle JRE, but OpenJDK should work, too.)

For Omero 5.2.x please use the old Orbit version.

Download the orbit_mac_xxx.zip to your desktop and double-click to extract its contents. Then you should have the OrbitImageAnalysis.app icon on your desktop which you can double-click to start Orbit.

The zip file can be deleted then.

For Omero 5.2.x please use the old Orbit version.

Tested with Oracle JRE >= 1.7. However, starting from version 2.5.x OpenJDK should work, too.

Extract the zip into a folder and start the program with

java -Xmx3g -XX:MaxPermSize=150m -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -cp "*" com.actelion.research.orbit.imageAnalysis.components.OrbitImageAnalysis

Set the -Xmx to a proper value according to your system memory.

Post Installation

If you have an image server like Omero you should configure Orbit to connect to it.
