What do we need to add, and how?
It is fully possible to establish an OMERO.server based on the one used in Dundee for teaching (also called “Virtual Microscope”),. The easiest way to replicate the whole server setup is to use the ansible administration software and the following ansible playbook . If you are not able or willing to use ansible, the ansible playbook is still useful, as it contains all the necessary configuration changes which are to be made on any OMERO.server to “turn it into” a teaching server with identical features to the “Virtual Microscope” in Dundee.
There might be a case (less ideal) that you want to add the features of “Virtual Microscope” to an existing OMERO.server, which would thus be a “mixed use” server (partially, perhaps, for research data, partially for teaching purposes). If this is the case, then please let us know, and can discuss the possibilities of such setup further.
This includes importing our current images into the OMERO system. Our images were generated using a 3DHistech scanner, so they are in the Mirax format. Our current virtual microscopy system converts them to the ECW format. Thus, these two formats are currently available.
There is no direct way to import your images in their original file format into OMERO. What you will need to do is to convert them into a supported multi-resolution image format e.g. OME-TIFF. A pipeline allowing to convert Mirax datasets into OME-TIFF is described at Converting Whole Slide Images to OME-TIFF: A New Workflow | Glencoe Software, Inc.
.The conversion is a two steps process:
- First convert the images into “raw” images using the Command line tool bioformats2raw 
- then run the Command line tool raw2ometiff to convert the “raw” images into OME-TIFF images.
The two Command lines tools can be installed directly from the GitHub repositories  or using conda .
Once converted into the OME-TIFF format, the images can be imported into your OMERO.server.
All the best
