WebHuman vs. mouse (left ) as well as stimulated vs. control (right) same type cells form distinct clusters, from Butler et al., Nat. Biot. 36, 411–420 (2024) Batch-effects can be genome-wide, i.e. present for majority of genes, or gene-specific, i.e. certain genes happen to be influenced by the batch.The former is very easy to see from the dimension reduction … WebAbstract. A variety of single-cell RNA-seq (scRNA-seq) clustering methods has achieved great success in discovering cellular phenotypes. However, it remains challenging when the data confounds with batch effects brought by different experimental conditions or technologies. Namely, the data partitions would be biased toward these nonbiological ...

In molecular biology, a batch effect occurs when non-biological factors in an experiment cause changes in the data produced by the experiment. Such effects can lead to inaccurate conclusions when their causes are correlated with one or more outcomes of interest in an experiment. They are common in many … See more Multiple definitions of the term "batch effect" have been proposed in the literature. Lazar et al.
