I have single cell data from one sample that I am trying to run through the Seurat pipeline. After having obtained the UMAP plot, I am trying to compare it to the PHATE plot. However, I can't seem to run PHATE on a Seurat object. What are some ways I can go about this? Can I convert my Seurat object to some other data type and run the function on it? is there a PHATE function in Seurat?
