Hello, I try to find outliers in my RNA-seq data (sample in columns and gene in row).
I run se <- deseq().
I use assays(se)[["originalCounts"]] but it return NULL. Is it because I don't have any outliers or because the function didn't work on my data ?

Yes sorry. I would like to prepare my data to do a survival analysis. For this, I keep differentially expressed genes that have been pre-filtered. I will want to be sure not to keep data with outliers for my study.
