edgeR for unequal replicated samples
Hi folks,

I have a question about how to do DE analysis of an unequal replicated RNA-Seq data? The design looks like:

Treatment 5day 7day 9day
A 1rep 3reps 1rep
B 1rep 3reps 1rep

The interest is to see the difference between treatments and over time.

Can edgeR handle that? Or any other recommended programs?

I appreciate a lot!

If I understand you correctly, you have multiple replicates at 7 days but not at 5 days or 9 days.

edgeR handles that automatically. All it requires are replicates for at least one condition. There is no requirement for equal numbers of replicates at each time or treatment.

All times are GMT -8. The time now is 10:16 AM.
