Hi all,

Hi Pedro,

When asking for help with third party plugins, it is very helpful to
explain:

1. What is this plugin / Where is the website.
2. Where you got the plugin / How you installed it (e.g. downloaded and
copied into ImageJ 1.x manually, or enabled an ImageJ update site in
ImageJ2/Fiji).
3. Steps for reproducing the failure you are seeing.

I assume you are talking about this plugin by Thorsten Wagner and Jan Funke:
  https://github.com/thorstenwagner/ij-irregular-watershed

Which I infer was forked from a function of Jan Brocher's BioVoxxel toolbox:

https://github.com/biovoxxel/BioVoxxel-Toolbox/blob/ebb8f9a66e12cab964c2b55e5e0e341174b6cafa/Biovoxxel_Plugins/src/main/java/de/biovoxxel/toolbox/Watershed_Irregular_Features.java

The ij-irregular-watershed plugin has a dependency on a library called
ij_blob:

https://github.com/thorstenwagner/ij-irregular-watershed/blob/123760d3fd759d52cd9bfabafc6aef3e963dac15/pom.xml

Your error message strongly suggests that the needed ij_blob dependency is
missing from your ImageJ installation.

- Did you build it yourself and install into ImageJ 1.x?
- Or maybe you turned on the ParticleSizer update site, which ships the
ij_irregular_watershed library, but seems to be lacking ij_blob?

You can find the ij_blob source code here:
https://github.com/thorstenwagner/ij-blob
And the IJ Blob wiki page at: https://imagej.net/IJ_Blob

I have CCed the author Thorsten Wagner.

Thorsten: should ParticleSizer ship ij_blob? What is the recommended
installation route for ij-irregular-watershed? I could not find any
documentation about it, nor any installation instructions on the IJ Blob
wiki page.

Thanks,
Curtis
