Yes, I was referring to the usage of the emptyDrops () function on the combined sce object where we read both batches together (control-case) using read10xCounts (). We observed that that rescued nearly ~3000 more cells in total (control+case) than when they were preprocessed separately. But now I know that's not the right way.

Web5.1 Packages for scRNA-seq Analysis. There are several possible software packages (or package “ecosystems”) that can be used for single-cell analysis. In this course we’re going to focus on a collection of packages that are part of the Bioconductor project.. Bioconductor is a repository of R packages specifically developed for biological analyses. It has an … Web此时，我们需要再安装spatstat.data这个包： > install.packages('spatstat.data') 当安装spatstat.data包时，可能还会出现spatstat.utils和spatstat.data版本不适配的问题，导致spatstat.data无法正确被安装。 安装时报错信息： Error: package or namespace load failed for ‘Seurat’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i ... fnaf scary art
