Abstract

Single-cell transcriptomics has transformed our ability to characterize cell states, but deep biological understanding requires more than a taxonomic listing of clusters. As new methods arise to measure distinct cellular modalities, a key analytical challenge is to integrate these datasets to better understand cellular identity and function. Here, we develop a strategy to "anchor" diverse datasets together, enabling us to integrate single-cell measurements not only across scRNA-seq technologies, but also across different modalities. After demonstrating improvement over existing methods for integrating scRNA-seq data, we anchor scRNA-seq experiments with scATAC-seq to explore chromatin differences in closely related interneuron subsets and project protein expression measurements onto a bone marrow atlas to characterize lymphocyte populations. Lastly, we harmonize in situ gene expression and scRNA-seq datasets, allowing transcriptome-wide imputation of spatial gene expression patterns. Our work presents a strategy for the assembly of harmonized references and transfer of information across datasets.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • When cell-type-specific batch effects are present, or there is a shift in the percentage of cell types across experiments, non-linear batch effect correction strategies are needed.

    “but note that when cell-type-specific batch effects are present, or there is a shift in the percentage of cell types across experiments, non-linear batch effect correction strategies are needed [18].”

    From Normalization and variance stabilization of single-cell RNA-seq data using regularized negative binomial regression (2019) · cites this paper as [18]

    In Results, “Constructing integrated atlases at the scale of organs and organisms” (page unavailable), the paper describes a non-linear, locally weighted correction and reports that it remains robust when cell types are absent from some datasets. It does not say that non-linear strategies are necessary when batch effects differ by cell type or cell-type percentages shift across experiments. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Samples were evaluated for potential batch effects and integrated using the Seurat Integration workflow with SCTransform normalization.

    “After merging, the samples were evaluated for potential batch effects.”

    From cGAS–STING drives ageing-related inflammation and neurodegeneration (2023) · cites this paper as [60]

    The Results section describes evaluating dataset mixing after Seurat v3 integration, and STAR Methods describes its batch-correction workflow. But the paper does not establish that the citing authors evaluated their samples after merging; STAR Methods instead specifies log-normalization, not SCTransform normalization. No page numbers are available in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Batch effects were corrected using FindIntegrationAnchor() and IntegrateData() in the reciprocal PCA approach of the Seurat workflow.

    “Batch effects were corrected with the FindIntegrationAnchor() and the IntegrateData() function in the reciprocal PCA approach of the Seurat workflow.”

    From TBX3 is dynamically expressed in pancreatic organogenesis and fine-tunes regeneration (2023) · cites this paper as [78]

    The STAR Methods (Method details; page unavailable) identify FindIntegrationAnchors as an anchor-identification function and IntegrateData as part of the integration procedure used for batch correction. But the paper describes CCA, not reciprocal PCA, as the initial dimension-reduction method for reference integration. It therefore supports the Seurat functions and batch-correction approach, but not the specified reciprocal-PCA workflow. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The hdWGCNA R package extends the data structures and functionality of the Seurat package.

    “the hdWGCNA R package extends the data structures and functionality of the widely used Seurat package,5,6,7”
  • hdWGCNA was developed as an R package extending Seurat and has an extensive documentation website demonstrating its use on new datasets.

    “To maximize usability among the genomics community, the hdWGCNA R package extends the data structures and functionality of the widely used Seurat package,5,6,7 and we developed an extensive documentation website for hdWGCNA demonstrating its use on new datasets.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
