In my Fiji, I seem to be unable to find that class. Feel free to call the

Thanks Johannes! I just figured it out - I already had ~/wekafiles

Trainable Weka Segmentation is working now.

That is really useful information! Would you mind adding that to the wiki
page at http://imagej.net/Trainable_Segmentation?
