Kbet batch effect

Webba batch effect, there is no systematic understanding of how batch effects manifest in single cell data and how much they can vary. Key aspects that characterize batch complexity are the strength of the batch effect with respect to other sources of variation and the cell type specificity, for example, storage conditions could cause higher WebbWe will look at how different batch correction methods affect our data analysis.
