Abstract

The normalization of RNA-seq data is essential for accurate downstream inference, but the assumptions upon which most normalization methods are based are not applicable in the single-cell setting. Consequently, applying existing normalization methods to single-cell RNA-seq data introduces artifacts that bias downstream analyses. To address this, we introduce SCnorm for accurate and efficient normalization of single-cell RNA-seq data.

  • SCnorm utilizes quantile regression to treat distinct gene groups separately, but ignores zero values which predominantly characterize droplet-based scRNA-seq.

    “Their method utilizes quantile regression to treat distinct gene groups separately, but ignores zero values which predominantly characterize droplet-based scRNA-seq.”

    From Normalization and variance stabilization of single-cell RNA-seq data using regularized negative binomial regression (2019) · cites this paper as [6]

    The Abstract describes quantile regression and separate normalization of groups of genes. ONLINE METHODS > SCnorm defines the regression input as non-zero expression counts, supporting the statement that zero values are excluded from that step. Our copy does not establish that zeros predominantly characterize droplet-based scRNA-seq specifically. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The authors of SCnorm reached similar conclusions in the normalization of non-UMI-based single-cell RNA-seq data.

    “Indeed, the authors of SCnorm [6] reached similar conclusions in the normalization of non-UMI-based single-cell RNA-seq data.”

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.
