@aditya-sarkar441, as I downloaded and checked that dataset - please remove the proteome expression in that data, by command such as adata = adata[:, ~adata.var_names.str.startswith("AB_")]
ok. why do we remove this proteome data ?
I got these cell types : ILC, Tcells, Monocytes, B cells. Why am I not getting NK and subtypes of T cells (CD4T, CD8T) ? Also how can i keep only those cells which are predicted as T cells ?
@aditya-sarkar441, the prediction is purely based on gene expression, so proteome data should be removed. There should be subtypes showing up, did you select the right model (for example, Immune_All_Low)?
Yeah, I selected Immune_All_High

@ChuanXu1 My Postdoc mentor is telling me that celtypist can predict dozens of cell types. I am not sure how to do this. Can you please help me with this ?
This is the command I'm using : pred_cont = celltypist.annotate(nature_cont, model = 'Immune_All_High.pkl', majority_voting = True)
@aditya-sarkar441, as I said, you can choose the "Immune_All_Low.pkl" model instead of "Immune_All_High.pkl"
Ok thanks, I'll try this out.
I tried running celltypist on the anndata object and it wqs giving me this error. The data is from a research paper : https://github.com/scCOVID-19/COVIDPBMC/
Error:
Exception: Invalid expression matrix, expect log1p normalized expression to 10000 counts per cell
Can you please help me out with this?
