    "description": "Two-channel spot colocalization (Cy3-like / Cy5-like nucleosome staining). Ported from the CellProfiler ExampleColocalization.cppipe example. Channel 0 = OrigStain1 (files *_N_R), Channel 1 = OrigStain2 (files *_N_G), merged into one 2-channel TIFF per site via Fiji. Object counts run ~10-15% off CP and coloc% ~5pt high, mainly because evanalyzer's watershed declumping (prominence-based) splits touching spots differently than CP's fixed-radius local-maxima method, and evanalyzer's illumination correction averages over blocks before fitting (more robust to bright spots) instead of fitting the raw pixels directly like CP does.",
