Compare

Track x Track → Track. Differential analysis between conditions.

The Compare layer aligns two tracks and computes per-region statistics using module-level functions.

Workflow

1. Align — align_tracks() pairs regions across two tracks by name (exact mode) or by binned overlap.
2. Compare — interval_fold_change() consumes aligned pairs and produces an IntervalTrack with comparison statistics in the tags.

from seqchain.compare import interval_fold_change

result = interval_fold_change(control, treated)

# Each result Region has tags: fold_change, log2fc, mean_a, mean_b
