Hi, Iam following the tutorial Orchestrating Single Cell Analysis, and in chapter 9.4 I try to run in R studio in my computer the

set.seed(101001) nmf.zeisel <-runNMF(sce.zeisel, ncomponents=10, subset_row=top.zeisel) but It takes about 10 min to converge. Is it normal? I am using a MacBookPro with 8GB of RAM. Thank you very much for your help. Sofía
