Dear Forum,
I've tried to migrate to the 3D Weka Segmentation Tool for segmenting
volumes of sediments into particles and matrix. This looks like it might
overcome slicing artefacts I have often experienced when using the previous
versions of the Weka segmentation tools.
I'm finding that a number of the training features cause JAVA exceptions and
errors: notably; Hessian, Derivatives, Structure, Laplacian and Edges
(occasionally). These all generate an instant error similar to this:
java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException:
Argument out of range: 1
java.util.concurrent.FutureTask.report(FutureTask.java:122)

I am not sure whether I have failed to add a key update site to FIJI, or
whether there is another issue: I am running FIJI/ImageJ version
2.0.0-rc-65/1.51s on an iMac running Mac OS 10.13.3.
Can anyone help here?
Regards,
Simon
