Good morning, I have a doubt about the microarrays analysis (Affymetrix). After obtaining the signal data with RMA, these they are in base log2. My question is the following one: If I have 3 replycates, is it convenient to calculate Fold Change starting from the stocking of these sign values in log2, and did the one also p-value with these values in log2, or however it is better to work with the data in natural scale.? Thank you, Sorry for my english. _________________________________________________________________ Tecnolog?a, moda, motor, viajes,?suscr?bete a nuestros boletines para estar siempre a la ?ltima enance&Brand=WL&RU=http%3a%2f%2fmail.live.com
