Yes, it's possible to cluster based on ADTs. Here is how it works:
1- get you ADT names from the main data slot:
grep("^ADT_", rownames(my.obj@main.data),value=T)
# [1] "ADT_CD3" "ADT_CD4" "ADT_CD8" "ADT_CD45RA" "ADT_CD56"
# [6] "ADT_CD16" "ADT_CD11c" "ADT_CD14" "ADT_CD19" "ADT_CD34"
MyADTS <- grep("^ADT_", rownames(my.obj@main.data),value=T)
2- Run PCA based on ADTs and all is good. Because, tSNE and UMAP will be running based on PCA the rest of your analysis will be based on ADTs.
my.obj <- run.pca(my.obj, method = "gene.model", gene.list = MyADTS, data.type = "main")
Hi I was wondering if it is possible to cluster on the ADT data alone, and if so, how to go about it? When I try using Seurat and PCA I get a warning message "The object only has information for 25 reductions" since we have only run 25 Abs, and subsequently we only get 1-2 PC's.
If I try using creating a distance matrix as per the seurat vignette the object is too large and the computer will not accept it. Is it possible in iCellR?
