Dear Bioconductors, I have been started to analyse my cDNA spot slides on ArrayVision and I have a doubt: ArrayVision offers Density, ARM Density, Median Density, MTM Density, Volume and, AR Volume. Here [1] there are an explanation about each one. How these ones is more appropriated to subsequent analysis on Bioconductor? I found a step-by-step here [2] and it use Volume. Could you suggest me anythings about it? 1. http://www.vision.ime.usp.br/~rvencio/Tcruzi/Hybridization_data/3%20-% 20measurement_description.txt 2. http://bioinformatics.mdanderson.org/prot-create-arv.html Thank you very much Marcelo
