Based on this plot, we would regress out the variation due to cell cycle. Apply regression variables. Regressing variation due to uninteresting sources can improve downstream identification of principal components and clustering.

WebJun 19, 2024 · This data correction can be performed by a simple linear regression against a cell cycle score as implemented in the Scanpy and Seurat platforms (Butler et al, 2024; Wolf et al, 2024) or in specialized packages with more complex mixture models such as scLVM (Buettner et al, 2015) or f-scLVM (Buettner et al, 2024).
WebMar 27, 2024 · Your PCA and clustering results will be unaffected. However, Seurat heatmaps (produced as shown below with ) require genes in the heatmap to be scaled, to make sure highly-expressed genes don’t dominate the heatmap.
