If you want advice on how to analyze your data, you need to tell us what 
_exactly_ you want to do. What is the experimental design? What is the 
biological question? What do _you_ mean by "differentially expressed 

I point this out because there is no one single way to analyse RNA-Seq 
data, especially not when time series are involved.

I'm also bit puzzled by your question. You do not have replicates and 
you have already found out that there is a section "working without any 
replicates". Also, you have _four_ time point, so the section "between 
_two_ experimental conditions" is clearly not applicable.
