WebJan 1, 2024 · This is useful when batch information is complicated by other differences, as is the case for data collected from different tissues: these experiments are different both biologically and technically. However, in most cases, the mixed information can also serve as a batch label to guide tools like LIGER, Harmony and Seurat for batch correction. WebKorsunsky et al. (2024) compared the runtimes for different batch correction methods and reported Harmony as one of the fastest batch correction methods, which took 68 min on 500,000 cells. One reason for the ability of quick batch correction by deepMNN was likely that it removed batch effect in one step. Another reason might probably be that ... the mutant movie
