Not sure if anyone else has noticed this, but while demonstrating multiplex classifiers to a couple of users, I noticed that running the Composite classifiers often does not show up in the Workflow, but I could not figure out why for quite some time.
I have now pinned it down to being a “first time opening a project” thing, and needing to run a single feature classifier first. If I
create and save any number of single measurement classifiers
save the image data
and then create a composite classifier
Running that composite classifier does not show up in the workflow for new users to access in their scripts. Only by running/applying one of the single measurement classifiers does the composite classifier show up when run.
This whole series of events only happens the first time a project is created. If I close the project and re-open it, the composite classifier shows up in the workflow just fine. But that first time in a project, the user needs to save and apply a single measurement classifier before any classifiers will show up in the workflow.
