<br>
I'm puzzled of how to convert slides acquired with Ariol[1] and stored as a *.cat file can be converted to a more portable file format such as png or jpg. Unfortunately Bio-formats seems not to support this type of file and google didn't retrieve possible solutions. Any hints?<br>

I also got an example files (628MB).<br>
Greetings,<br>
Andreas Heindl<br>
