Can I Performing scGSEA by using Seurat object?

[m9994]

In tutorial, program looks like start from RAW counts matrix.
Can I use normalized Seurat object which have already done PCA UMAP?

data("small_BC_atlas")

data <- gficf( M = small_BC_atlas)

data <- runPCA(data = data,dim = 10,use.odgenes = T)

data <-runReduction(data = data,reduction = "umap",nt = 2,verbose = T,n_neighbors=150)

It would be better to do it the other way around. You could start from the raw count, perform scGSEA using the gficf package, and then integrate the results with Seurat.
