This documentation is for the new OMERO 5.3 version. See the latest OMERO 5.2.x version or the previous versions page to find documentation for the OMERO version you are using if you have not upgraded yet.
The following documentation is for developers wishing to write OMERO client code or extend the OMERO server. Instructions on downloading, installation and administering OMERO can be found under the System Administrator Documentation of the main site.
OMERO is an open source client/server system written in Java for visualizing, managing, and annotating microscope images and metadata. The OMERO Application Programming Interface allows clients to be written in Java, Python, C++ or MATLAB. OMERO releases include a Java client OMERO.insight, a Python-based web client OMERO.web and the Command Line Interface as an OMERO development tool, which also uses Python. There is also an ImageJ plugin. OMERO can be extended by modifying these clients or by writing your own in any of the supported languages (see figure). OMERO also supports a Scripting Service which allows Python scripts to be run on the server and called from any of the other clients.
OMERO is designed, developed and released by the Open Microscopy Environment, with contributions from Glencoe Software, Inc. OMERO is released under the GNU General Public License (GPL) with commercial licenses and customization available from Glencoe Software, Inc.. You can read about how OMERO has developed since the project started in the OMERO version history.
For help with any aspect of OMERO, see details of our forums and mailing lists.
With the release of OMERO 5.3.0, the OMERO.insight desktop client has entered maintenance mode, meaning it will only be updated if a major bug is discovered. Instead, the OME team will be focusing on developing the web clients. As a result, coding against this client is no longer recommended.
OMERO can be extended by modifying these clients or by writing your own in any of the supported languages.
