Finds features that pair across an unlabeled (12C) / uniformly 13C-labeled experiment on the m/z + n·1.00335 carbon ladder, driven off a GNPS2 everything-bagel task's aligned_features.csv. Two modes below — one merges the 13C-Labeling Prioritizer (rank features for discovery) and IsoPairFinder (WT-vs-mutant pathway intermediates). Ported from the FeatureFinding desktop app; re-sourced to read the task directly.
Reads aligned_features.csv and pulls per-feature XICs from the task's /resultfile + /xic APIs over CORS — nothing is uploaded. Needs a run whose samples include paired unlabeled (12C) and uniformly 13C-labeled files. You can also deep-link with ?task=<id>.
Nothing in the data marks a sample as labeled or as case/control — that's design, not measurement. Labels below are auto-guessed from the sample column names; fix any that are wrong. 13C is guessed from the literal substring 13C; group from the case/control label prefixes.
