bcmvn<-find.pK(sweep.stats) NULL

[ramikheireddine]

sweep.res <- paramSweep_v3(SeuratOb, PCs = 1:20, sct = FALSE)
sweep.stats <- summarizeSweep(sweep.res, GT = FALSE)
bcmvn <- find.pK(sweep.stats)

I am getting Null as a pK value.
Can you help me understand how to fix this.

NULL is the usual terminal output for that command; did you check the bcmvn variable? It should be a dataframe. Find the row under the BCmetric column with the highest value, and use the corresponding pK.
