Correction to: Communications Biology https://doi.org/10.1038/s42003-021-02320-w, published online 30 June 2021.

In the original version of the Article, reference 29 contained errors in the journal name, page numbers, and second author’s initials. The incorrect reference shown was:

Xi, N. M. & Li, J. Y. Benchmarking computational doublet-detection methods for single-cell RNA sequencing data. Sci. Direct 12, 1–19 (2020).

The correct reference is:

Xi, N. M. & Li, J. J. Benchmarking Computational Doublet-Detection Methods for Single-Cell RNA Sequencing Data. Cell Syst. 12, 176–194.e6 (2021).

In addition, the page numbers provided in references 15 and 16 were incorrectly given as 316689 – 331700 and 294 – 319, respectively. The correct page numbers are 31689-31700 (reference 15) and e00294-19 (reference 16).

The errors have been corrected in the HTML and PDF versions of the article.
