Deleted:normalize for sample size in single cell rna seq cluster frequencies data

Question

[chi.delta]

Hello,

I have some single-cell RNA seq of different mice tissues and two different conditions (treated, untreated). After generating the UMAP plots and the resulted cells clusters I would like to calclute the frequency of treated vs untreated in each respective cluster. However, the initial sample (of treated and untreated) sizes are not equal. How can one normalize for this?

Thanks a lot
