I have a RNA seq data which I am trying to identify DEGs. Dataset contains Untreated - 2 replicates (time point 0hr) Treated - 4 replicates (2 replicates at 6hr and 2 replicates at 12 hr) I merged all the samples and tried to identify DEGs untreated vs treated as well as I compared the samples using LRT to find the changes at any time point.
After doing the LRT test, to identify the significant genes the cutoff used was adjP<0.05. Approximately 10000 genes were obtained after cutoff. Can you use rlog transformation as normalization on these 10000 genes for gene co-expression network construction. Does doing LRT test will make any change in construction of a co-expression network
