WebVice versa, careless correction of batch effects can result in loss of biological signal contained in the data [6–8]. Proper handling of batched data is thus paramount for successful and reproducible research. Various methods have been developed to detect or even remove batch effects in genomics data, particularly RNA-seq data and cDNA ... WebIn molecular biology, a batch effect occurs when non-biological factors in an experiment cause changes in the data produced by the experiment. Such effects can lead to inaccurate conclusions when their causes are correlated with one or more outcomes of interest in an experiment. They are common in many types of high-throughput sequencing …
