Dear list, I have got the raw counts for each exon using HTSeq-count. I want to use DESeq to normalise the counts. How can I output the Normalised count data from DESeq? Thank you

Hi Fabrice, when you use DESeq after normalizing you get the size factors. I think that if you divide your count data by the size factor you get the normalized count.

Hi Fabrice, you can use counts(x, normalized=TRUE) For more info, have a look at the manual page of the 'counts' accessor function.
