Have you read through the user's guide that comes with edgeR?


There's lots of very useful stuff to be learned there w.r.t analyses
of RNA-seq data, so you should definitely do so.

There is even a section entitled "What do do if you have no
replicates." If you still have questions after you've read through
that guide, then please post with specific questions regarding
particular steps of the analysis you are having trouble with.

If you are new to these types of analyses, reading through the user
guides that come with limma and DESeq2 will be very informative as
well, and highly recommended.
