Webb27 jan. 2024 · Sctransform is based on the observation that there seems to be an almost linear relationship between the UMI counts and the number of genes detected in a cell. … WebbNow, using our SCTransform object as input, let’s perform the integration across conditions. First, we need to specify that we want to use all of the 3000 most variable genes identified by SCTransform for the integration. By default, this function only selects the top 2000 genes. Webb23 dec. 2024 · Our approach can be applied to any UMI-based scRNA-seq dataset and is freely available as part of the R package sctransform, with a direct interface to our single-cell toolkit Seurat.
