Compute features option not working in Mastodon

[sundar07]

Hi Jean Yves,
I have been using Mastodon plugin in FIJI to track cells manually in zebrafish embryos. When I finished tracking and went for “Compute Features” option, I get the following error:

Exception in thread “Feature computation thread” java.lang.NoClassDefFoundError: io/humble/ferry/AtomicInteger

I have updated java, updated fiji, tried uninstalling and re-installing Mastodon, but still have the same problem. Any suggestions?

Thanks
Sundar

Hi Stefan,
Thanks for your reply. I am very much an end user and I do not particularly understand how to change what you have suggested. Can you detail this a bit more? Or does this change has to happen from Mastodon's end?

Currently this dependency is needed: https://sites.imagej.net/Humble-Video/jars/humble-video-noarch-0.3.0.jar-20221115102504

It works now! Thanks a lot for the work around!!

It is an import error. I imported AtomicInteger from humble video, while I should have imported the one in java.lang.
I did not see the error because I am distracted and I had humble video in my class path when compiling.
I am so sorry >.<
