ProjectCells(dge_train, dge_test, genes.use = dge_train@var.genes,
  regressout = c("IG1.S", "S", "G2.M", "M", "M.G1"),
  to_project = "pseudotime", k = 25, pc.use = 1:25, test_mode = F)

`dge_train`	Seurat object with 'pseudotime' field included.
`dge_test`	Seurat object. Cells will be assigned a pseudotime value based on 'dge_train'.
`genes.use`	Defaults to 'dge_train@var.genes'. If you use method="PCA", use the same genes here. If you aren't sure, use method="KNN".
`regressout`	Please put whatever you used for 'latent.vars' in RegressOut when you processed 'dge_train'.
`to_project`	Character vector such that FetchData( dge_train, to_project) contains numeric columns. Try "pseudotime" or c("tSNE_1", "tSNE_2").
`k`	Number of nearest neighbors to use.
`pc.use`	which principal components to use for nearest neighbor search.
