Create an assay with seurat v5 but lost the col names and row names

[baliaga31]

Dear Seurat community,

I did a script with Seurat v5 to study TF activities in my 10X dataset. See below.

for (i in 1:length(r1.clustMats)) {
  tfs <- CreateAssay5Object(r1.clustMats[[i]])
  tfs <- NormalizeData(tfs)
  tfs <- ScaleData(tfs, features = rownames(tfs))
  TF.metacells[[i]] = viper(tfs@layers$scale.data, r1.net, minsize = 5) 
}

r1.clustMats is a Large List, which contains 4 "matrix" "array". It's a scaled.data. I can access them with r1.clustMats[[1]] with genes for rownames and cells for colnames.

When I created an Assay with CreateAssay5Object, I lost the the rownames and the colnames. Then I can't run viper.

How to keep the rownames and the colnames when I create the assay?

Thank you for your help.
