VSI Reader ActionBar

O.Burri, R. Guiet

This ActionBar provides simple access to our Olympus Slide Scanner .VSI Files. Includes tools for extracting and resizing whole tissue scans.


Fast tiling microscopes are becoming commonplace but often rely on closed-source and closed-format systems to access the data.

This was the case with the Olympus Virtual Slide Scanner microscope. We needed a way top open and process the large (>100k pixels) images generated by the software in Fiji.

The result is an ActionBar that encompasses most common tasks required when opening and dealing with these large datasets: ROI management, On-demand navigation and batch-processing.

You will need Jerome Mutterer's excellent ActionBar Plugin Installed if you're going to use the VSI Reader.
