DEXSeq - multiple conditions

Hello, I have 37 RNA-seq datasets for 18 human tissues - some have 3 replicates, some 2 and some do not have any (sorry to say that). I'm thinking of a way to do differential exon usage analysis - using DEXseq. I could not see any example in the documentation where multiple conditions are compared (eg., tissues) other than pairwise comparisons (this is not a case-control kind of study). In edgeR, I was able to use the ANOVA-like test for getting differentially expressed genes (across all 18 tissues). I was wondering if there is such a test I could do with DEXseq. Thanks, Manoj.

Hi Manoj, If you don't do anything special, the normal testForDEU should do what (I think) you want, which is to test if there is *any* dependence of exon usage across all conditions at once.

Thank you Steve. I wasn't entirely sure about it.
