Dear Biostars: I'm a newbie in RNA-Seq and I'm trying to understand the different parts of the analysis. After reading papers, manuals, tutorials and basically whatever comes to my screen, it didn't manage to find "diagnostic" test(s) to run after a differential gene expression analysis. This, in order to know if the p-vals I'm obtaining are "correct" or following a distribution or fits better to one (or several) of the models I'm specifying... or are just the results of pressing some buttons. I understand that the DGE analyses are more complex than SNP association tests, but in the GWAS world, a QQ-plot could tell me if the p-vals I was obtaining were following a normal distribution.
So, in brief, is there any "Diagnostic" analysis to know if my results are ok after a DGE analysis? (comments and suggested lectures are welcome)
Thanks in advance!
