I used DESeq to identify differentially expressed genes between two timepoints, data is from high-throughput sequencing, without (!) replicates.
My starting dataset has 1734 genes. Of these, 1678 have a pval < 0.05. *All* genes have a padj (p values, adjusted for multiple testing with the Benjamini-Hochberg procedure) of 1.
I am confused by this result and don't know how to interpret it: why are so many genes considered significant(ly differentially experssed)? And, although almost all genes are considered significant, all genes without exception are actually not significant after adjustment for multiple testing?
