Error in reconstruction after Class3D with reorder classes on

3D Classification
1

Hi,

I’m not sure if this qualifies as a bug or working as designed, but the issue is as follows:

  • I have a long-running 3D classification with many classes, one of the classes, let’s say class 50 during the classification looks promising, so I would like to queue up a reconstruction and local refinement while the job is running.
  • When classes are re-ordered at the end of the job, the class number changes - let’s say to class 10.
  • This creates an issue. The class number specified at queue time is class 50, so it is not totally clear what will happen - will it take the final class 50 (not what I want) or the final class 10 (correct)?
  • Answer is it does neither, it fails with the attached error.
  • If the reconstruction is queued after Class3D completion, everything works as expected.

Cheers
Oli

Hey @olibclarke,

Unfortunately, I think this falls under ‘working as designed.’ Without some significant backend restructuring, the only way you can queue a reconstruction on a specific class is if you turn off class re-ordering.

The error you’re seeing is due to a unique id mismatch between the connected dataset (when queued) and the dataset that ends up in the slot after re-ordering.

Got it, thanks! Figured it might be that but thought I’d check :slight_smile:
