Before you begin
This phase expects a reviewed and corrected DTM CSV from Phase 3.1. Low-confidence cells (marked [?]) and any anomalous scores should be resolved in the CSV before uploading. The analysis proceeds in four steps: binarisation → TTM construction → cluster analysis → frame naming. Download the sorted TTM after Step 4.2 and compare it against the clustered output from Step 4.3 to validate the cluster structure before proceeding to naming.
