Figure Legend Snippet: OCR-driven Boolean rules for Spi1 are associated with cell-type-specific chromatin structures involved in its regulation. ( A ) ATAC-seq readouts within \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $\pm$\end{document} 100 kb of the Spi1 promoter identify candidate OCRs, and RNA-seq quantifies Spi1 expression levels across 85 cell types spanning nine blood lineages. ( B ) A double-OCR subset \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $\lbrace \mathrm{E}_{-12}, \mathrm{Promoter}\rbrace$\end{document} —including an enhancer located 12 kb upstream of the TSS and the promoter—predicts gene expression variability with the optimal BIC. In the circular heatmap, blood lineages are color-coded similar to panel (A); OCR accessibility, Spi1 expression, and Boolean rule values are shown, with cold colors representing low levels and warm colors high levels. ( C, D ) MSE and Boolean rule coefficients are shown as a function of the regularization parameter \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $\log (\lambda )$\end{document} in the fitted ridge regression model, where Boolean rules derived from the double-OCR subset are used as predictors of Spi1 expression. ( E ) Two boolean rules \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} $(\mathrm{E}_{-12} \wedge \mathrm{Promoter}) \ \mathrm{or}\ (\lnot \mathrm{E}_{-12} \wedge \mathrm{Promoter})$\end{document} receive positive coefficients, corresponding to chromatin structures associated with gene regulation in myeloid and B cells.

Figure Legend Snippet: Cell-type-specific OCR-driven Boolean rules predict gene expression from ATAC-seq data. ( A ) Heatmap of gene scores derived from 1194 cell-type-specific Boolean rules associated with 661 genes. The Boolean rules were selected based on differential gene score patterns across various blood cell lineages, reflecting cell-type-specific regulatory logic. ( B ) Corresponding RNA-seq expression levels for the genes shown in panel a, demonstrating strong concordance between the Boolean rule-derived gene scores and transcriptomic measurements. This comparison highlights the predictive power of the OCR-driven Boolean rules for gene expression across different cell types.
