摘要：Batch effects have been a long-standing problem in sequencing data analysis, significantly impeding the comparison of multiple experiment batches. Existing methods for batch effect removal and quantification emphasize cell alignment across batches, overlooking gene-level batch effects. Here, we introduce group technical effects (GTE), a quantitative metric to assess gene-level batch effects. Using GTE, we show the unbalanced gene-level batch effects in single-cell data. A subset of highly batch-sensitive genes (HBGs) is the main contributor to batch effects and varies across datasets, while non-highly batch-sensitive genes (non-HBGs) exhibit minimal batch effects. As few as three HBGs are sufficient to introduce strong batch effects to the data. Furthermore, biologically similar cell types undergo similar batch effects, informing the development of data integration strategies. The GTE method is versatile and applicable to various single-cell omics data types.
