Hi Tushar,
I recommend mean over median. Median tends to be uninformative as most genes have a median of zero. 10x data is not actually zero inflated, it is just negative binomial distributed (unlike Smart-Seq data does appear to be zero inflated). The mean of a sample from a negative binomial distribution is an estimate if the real population mean (unlike the median).
Hope that helps

Hi! Thanks for the great package.
I'm interested in running the cell type specificity score calculation for some 10x snRNA-seq datasets. Is there a clear reason to use either mean or median for zero-inflated datasets?
Also, curious for the rationale of dividing the median scores by colSums of the mean per cell type/subtype as opposed to the colSums of the median ("generate.celltype.data.R", lines 89/91)?
