Hi @Roger-GOAT ,
Looks like installation from satijalab/seurat is broken right now per https://github.com/satijalab/seurat/issues/4226.
You can fix this with
devtools::install_version("spatstat", version = "1.64-1")
and then try again to install my fork, which I've updated to Seurat 4.0.0.
devtools::install_github("scottgigante/seurat", ref="patch/add-PHATE-again")
If you can't install the fork, you can run PHATE on a Seurat object by doing the following:
assay = 'RNA'
data <- t(GetAssayData(object = seurat_data, slot = 'data', assay = assay))
phate_output <- phateR::phate(data)
# save PHATE result to csv
readr::write_csv(as.data.frame(phate_output))
# save PHATE result to Seurat
phate_output <- as.matrix(phate_output)
colnames(phate_output) <- paste0("PHATE_", 1:ncol(phate_output))
rownames(phate_output) <- rownames(seurat_data)
phate.reduction <- CreateDimReducObject(
embeddings = phate_output,
key = "PHATE_",
assay = assay
)
seurat_data[["phate"]] <- phate.reduction
Feel free to reopen if you're still having issues.
Thank you Scott. I don't know why I succeed to do this: devtools::install_github("scottgigante/seurat", ref="patch/add-PHATE-again") (I done this "spatstat", version = "1.64-1" before I submited this issue). But I get all the reduction image (tSNE,umap,PHATE) like this: I never met this before. Maybe some conflicts between packages.
Does this happen if you go back to the reference installation for Seurat?
Dear Dr.Gigante, I get great result from phate.R. However, I can't write the embedding back to Seurat object. Q1: devtools::install_github("scottgigante/seurat", ref="patch/add-PHATE-again"), error as below: Error in parse(con, keep.source = FALSE, srcfile = NULL) : 284:1: unexpected input 283: export(RunPCA) 284: << ^ Calls: ... withCallingHandlers -> loadNamespace -> parseNamespaceFile -> parse

Q2:If I give up to install this version of Seurat, how to write the Phate result into Seurat object? Or write a .csv file from py.phate result? I notice the there is more than one embedding in phate result.
Thank you for your time. Best!
