Hi Priscila,

Am I right that your data have 2 time points, each with a pair of dye-swap 
experiments? For each biological replicate, was it sampled repeatedly 
over time? Looks like timecourse can be used, as long as it's 
of longitudinal design. You can just flip the log2 ratio for Control X T 
so that you get two replicated vectors of log2 ratios.

Best,
Yu Chuan
