Hello all, I am working at the FORTH institute in Crete and it's been a long now that I am trying to reproduce the results of the paper : "Gene expression profiling predits clinical outcome of breast cancer", by Van't Veer et al. It has been published in NATURE, vol 415, 31 January 2002. http://www.nature.com/nature/journal/v415/n6871/full/415530a.html I am facing some difficulties in building the classifier and I was wondering if someone else has worked on it and could give me some help. Thank you all, Eleni [[alternative HTML version deleted]]
