I am looking for good RNA NGS tutorials of all sorts- any recommandation?
I read NGS tortillas... I'm now disappointed.
This question could use a lot more information about what exactly you want to do. In addition, just googling will give you plenty of results.
This has already been answered on Biostars - How Do I Get Started Working With Rna-Seq Data
And a more updated version for this question: Up-to-date RNA-Seq Analysis Training/Courses/Papers (Dec 2017)
I found RNA-seqlopedia very useful
