i made something that may help to address the problem described in the feature request: https://jumear.github.io/stirpy/lab?path=iNat_obs_with_disagreeing_ids.ipynb.
it’s a notebook that contains Python code, in a framework that should allow you to run and adapt the code from your browser (without having to set up a Python environment on your machine). hopefully there are enough comments in the script that you’ll be able to understand what it’s doing and be able to run it without too much effort. if anyone has any questions, please don’t hesitate to ask.
