Differential gene expression analysis with RPKM

Hi,

I know there are a lot of discussion about why we can't perform DE analysis (by EdgeR or DEseq )using RPKM, but this is the only data type I received from others. How can I perform DE analysis using the RPKM data I have now? Thank you!

de gene rpkm rna-seq

I did find the limma method online. I was wondering if there are other methods available. Since I can't get the raw counts, I guess I have to report the limma method even though it is not ideal. Thank you!

Ask for raw counts or if you do not have anything else than RPKM (or any other values that hopefully are somewhat properly normalized) then use limma-trend after transforming values to log2 scale, see section 15.4 of the limma user guide. In the future please use the search function, this has been asked a lot of times before.
