WebApr 17, 2024 · Like rescaleBatches, this function assumes that the batch effect is orthogonal to the interesting factors of variation. For example, each batch is assumed to have the same composition of cell types. The same reasoning applies to any uninteresting factors specified in design, including continuous variables. WebThe most common way to deal with batch effects is to attempt to remove them via normalization and/or batch effect-correction algorithms (BECAs). Unfortunately, we overestimate our ability to mitigate batch effects and new problems are emerging: e.g. incomplete removal of batch effects or botched removal attempts given uneven sample …
