  "Description": "A simple and unified evaluation toolkit for benchmarking\nsingle-cell and multiomics data simulation methods. Evaluates\nhow realistic simulated data are compared to real biological\ndatasets across three multiomics experimental designs: (i)\npaired multiomics (simultaneous co-assay from identical cells,\ne.g. 10x Chromium Multiome, SHARE-seq, SNARE-seq), which\nunlocks the full Category 7 cross-modal coupling suite\nincluding FOSCTTM alignment scores and peak-to-gene regulatory\nlinkage; (ii) unpaired multiomics (independent scRNA-seq and\nscATAC-seq profiled from separate cells of the same tissue),\nsupported through per-modality unimodal evaluation (Categories\n1-6, 8) and population-level cross-modal metrics such as\nco-expression module fidelity and network Jaccard similarity;\nand (iii) mosaic multiomics (partial co-measurement where only\na subset of cells has both modalities, e.g. DOGMA-seq or mosaic\npooling designs), handled by subsetting the paired cell\nfraction for coupling metrics and evaluating each modality\nindependently otherwise. The toolkit quantifies simulation\nrealism using 62 metrics organized into 8 easy-to-understand\ncategories: (1) Distribution Differences: Statistical distances\nbetween real and simulated values (such as KS, Wasserstein,\nMAD, and RMSE), (2) Summary Properties: Gene correlations, zero\ncounts, and dropout patterns, (3) Cell Structure and\nClustering: How well distinct cell types and clusters are\npreserved (such as Silhouette width, ARI, and NMI), (4) Batch\nand Confounder Mixing: How well technical batch variations are\ncaptured or mixed, (5) Biological Signals and Marker Genes:\nPreservation of differentially expressed genes (DEGs) across\nSimpipe, SimBench, and Shaky Foundations frameworks, (6) Cell\nLineage and Trajectories: Preservation of continuous\ndevelopmental pathways (inferred directly from scRNA-seq\ncounts), (7) Multiomics Relationships: Connections between\ndifferent layers (such as gene expression and chromatin\naccessibility) — fully active for paired data; population-level\nmetrics available for unpaired and mosaic data, (8)\nComputational Resources: Speed (runtime in seconds) and memory\nusage (peak RAM in MiB). Includes non-linear low-dimensional\ncell embedding projections (UMAP, t-SNE, PCA) with quantitative\ncluster separability (Silhouette) and fidelity (ARI) metrics,\nautomated score normalization, leaderboards, 600 DPI bubble\nplots, and an interactive Shiny app studio.",
