The first argument should be a Seurat object.
I see the problem. My code tries to search genes from `integrated` assay first, and then `RNA`. Since your data object doesn't have the `integrated` assay, it returns the error....
I quickly browsed my code and didn't see where I rescale the expression values. Could you check that in your data slot, the values are in the range of `2`...
Good to know the workaround works. Thanks for showing the solution!
