Apologies if this is considered as too much advertisement. The product advertised is offered for free, so I hope nobody is offended by this pitch:

I know several people on this mailing list are involved with whole slide images and virtual microscopy.

Virtual slides and whole slide images alike are hard to manipulate because they are often stored in proprietary file formats.
ImageJ and FIJI are great tools for image analysis, but lack the capabilities to read these specialized files.
As of today, we have a new version available for our HistoJ plugin. You can find more information about it on our updated website at https://free.pathomation.com/fiji

With PMA.start and the HistoJ plugin, you can bridge the two worlds and bring your microscopic observations into ImageJ and FIJI without breaking a sweat. See how it works in this video and start thinking about WHAT you want to analyze, rather than HOW you're going to do it in the first place.

We would love to get some feedback from members in this group.
