Jacques Retief (Sr. Manager Scientific Affairs at Illumina) has produced a phenomenal poster with graphics for over NGS 50 methods. If you've ever wanted to know how MAINE-seq, smMIP, ATAC-seq or just about anything else worked then Jaques helpfully provides a graphic of each method and the reference as well.
An image of the whole poster here would not do it sufficient justice so I'll stick to a few of the graphics and a link. Go get it, print it out and hang it on your bedroom wall!
