Hi when run this function: sc.pl.violin(
pro_adata, list(filter(lambda x: x== “ADT_CD45RA”, pro_adata.var[“protein_names”])), gene_symbols=“protein_names”,
groupby=‘leiden_totalVI’
)
I got an error: KeyError: “Could not find keys ‘[‘ADT_CD45RA’]’ in columns of adata.obs or in adata.raw.var_names.”.
I need help!
