Error：SCP::RunCellQC(srt = pancreas_sub)

[Crorazon]

May I ask how to solve this problem?

data("pancreas_sub")

pancreas_sub <- RunCellQC(srt = pancreas_sub) function 'as_cholmod_sparse' not provided by package 'Matrix'Error in srt[[paste0("db.", dbm, "_class"), drop = TRUE]]: ! ‘db.scDblFinder_class’ not found in this Seurat object

Backtrace:

1. SCP::RunCellQC(srt = pancreas_sub)
2. SeuratObject:::[[.Seurat(srt, paste0("db.", dbm, "_class"), drop = TRUE)

Hi @Crorazon, I also encountered the same problem after updating the version of seurat. I would like to ask what is your version of seurat?

According
#https://github.com/bwlewis/irlba/issues/70

install.packages("Matrix", type = "source") install.packages("irlba", type = "source")

works well for me.
