Reverse Normalized RNA-seq readcounts/fpkm values to raw readcounts

I received DESeq2 normalized readcount and FPKM values from our experiment, but the files containing our raw read counts are not present.

 

I need the raw readcount values, and was wondering if there is any way to reverse the values from normalized to raw?

There's not a good reason to do this if its your own experiment. The original data very likely exists, and someone should be able to help you access it. If not, it's really not that hard to regenerate the counts. The best pipelines can take about 3-5 minutes per sample to generate counts for DESeq2.

Thanks Michael,

Unfortunately our raw data was deleted off the server, which is why I can't access it. And I would like to re-run the analysis through EdgeR, because the analysis performed by the sequencing company with DESeq2 appears to be missing some genes that we feel are significantly differentially expressed by our calculations of readcount, although I want to adjust for FDR using appropriate algorithms.

 

Do you know where I can find these pipelines for reversing normalization?

No I don't have a recommendation for this.
