Hello all, I've written a pretty detailed description of the Geuvadis eQTL mapping methods in the wiki: http://sanabre.net/geuvadis/index.php/Basic_methodology By the way, when you're editing text, below the edit window there is a link to Editing help. I've written some instructions there, and please feel free to add more content if you've figured out a way to do some wiki editing that wasn't entirely trivial. best regards, Tuuli -- Tuuli Lappalainen, PhD Department of Genetic Medicine and Development University of Geneva Medical School CMU / Rue Michel-Servet 1 1211 Geneva 4 Switzerland Tel. +41-(0)22-3795550 tuuli.lappalainen(a)unige.ch
