Abstract

As single-cell RNA sequencing (scRNA-seq) technologies have rapidly developed, so have analysis methods. Many methods have been tested, developed, and validated using simulated datasets. Unfortunately, current simulations are often poorly documented, their similarity to real data is not demonstrated, or reproducible code is not available. Here, we present the Splatter Bioconductor package for simple, reproducible, and well-documented simulation of scRNA-seq data. Splatter provides an interface to multiple simulation methods including Splat, our own simulation, based on a gamma-Poisson distribution. Splat can simulate single populations of cells, populations with multiple cell types, or differentiation paths.

Claims other papers make about this one

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

  • Papers evaluating the performance of single-cell-specific tools all compute the simulations as if cells were independent.

    “Furthermore, papers evaluating the performance of single-cell-specific tools all compute the simulations as if cells were independent15–21.”

    From A practical solution to pseudoreplication bias in single-cell studies (2021) · cites this paper as [16]

    The Background (page unavailable) says many single-cell analysis packages use simulations to evaluate their performance, but does not say those simulations treat cells as independent. The Results sections on simulation models and differentiation paths describe Splatter’s own simulations, not a survey establishing that all tool-evaluation papers make that assumption. Searches for independent cells and intercellular dependence found no passage supporting the universal claim. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Significant marker genes are found even when clustering random data generated by splatter.

    “We thus find significant marker genes even when clustering random data generated by splatter (Zappia et al, 2017) (see Appendix Supplementary Text S3).”

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.
