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 … WebOct 16, 2024 · In this lab we will focus on data integration / batch correction apporaches specifically appropriate for single cell RNAseq datasets. We will go through the steps of 1. batch effect diagnosis, 2. actual correction 3. evaluation of the effects/quality of correction.

Batch effects in single cell RNA sequencing - GitHub Pages

Web1.1 Motivation. Large single-cell RNA sequencing (scRNA-seq) projects usually need to generate data across multiple batches due to logistical constraints. However, the processing of different batches is often subject to uncontrollable differences, e.g., changes in operator, differences in reagent quality. This results in systematic differences ...
