From: Marie on 18 Mar 2010 11:41 Dear all, I'm sorry to ask so basic questions but there are some things I don't understand... I have to do a project on microarrays and I have datas for hundreds of genes for different people (sick and healthy). My problem is that I don't know what to do from the beginning (I would like to find the most interesting genes to say: that's guy is healthy or not) but I don't even understand the PCA function in Matlab. Could you please help me? I know math but here I have some doubts on how to apply what I know on these real datas.... Thanks a loooooooooooooooooooot!
