WebTo address the limitations of existing methods, two recently developed batch effect correction methods, MNN and Seurat v3, adopt the concept of leveraging information of mutual nearest neighbors (MNNs) across batches [ 8, 12] and demonstrate superior performance over alternative methods [ 8, 12 ]. WebMutual nearest neighbors are pairs of cells from different batches that belong in each other’s set of nearest neighbors. The reasoning is that MNN pairs represent cells from the same biological state prior to the application of a batch effect - see Haghverdi et al. for full theoretical details. Thus, the difference between cells in MNN pairs ...
