Hi, when I select the "fixedNum" = 40000 cells as below fcs.data <- runExprsMerge(fcs.files, comp = FALSE, transformMethod = "none", mergeMethod = "fixed", fixedNum = 40000)

I get error message in cyt <- runFastPCA(cyt) Error in La.svd(x, nu = 0) : infinite or missing values in 'x' I looked at cyt@raw.data & cyt@log.data there are no missing values/NA. Can you help to solve it?

I should add when I reduce the numbers as default (ceil = 2000) then it works
