Single-cell RNA sequencing (scRNA-seq): filtering cells by transcript counts, how to choose cutoffs?
I am running a notebook with example for the MAGIC algorithm.
In the data preprocessing step, a filtering operation is required to filter out cells with a small count of transcripts.
My question is ...
