Analyze OMERO timelapse images using the TrackMate User Interface¶
In this example we open in Fiji an image stored in an OMERO server and use TrackMate to analyze it.
In this section, we show how to use TrackMate via its User Interface. The manual steps are essential to determine the suitable parameters to analyze the images. Note that when using the TrackMate User Interface, the generated tracks cannot be saved as ROIs into OMERO.server.
- Install Fiji on the local machine with the OMERO.insight-ij plugin. The installation instructions can be found in the Fiji guide.
Go to Plugins > OMERO > Connect To OMERO. This will show a login screen where you can enter the name of the server to connect to, the username and password. The OMERO plugin will allow you to browse your data in a similar manner to OMERO.web.
In the OMERO login dialog, click the wrench icon and then add the server address in the dialog. By default, only “localhost” is listed. Click on the plus icon to add a new line to the list and type into the line the server address.
Enter your credentials and click Login.
Browse the Dataset where your image to be tracked is located, e.g. artificial-trackmate.
Double-click on the FakeTracks.tif Image to open it in Fiji.
Make sure it is opened using the
Hyperstackviewer. This option depends on what you did last time when using your Fiji.
In case you are not sure, Open
Plugins > Bio-Formats > Bio-Formats importerand then select any image on your local computer to open it in Fiji. In the popup dialog, in the top left dropdown menu.
OK. Then, close and re-open the FakeTracks.tif Image from OMERO.
