Dear all,
i have microarray data of 3 classes of patients. It's not a time course experiment only steady state.
I used a rule-based method to classify the groups by the expression of the genes. This works out so far. Nevertheless I want to check my results with an other method. Therefore I look for one and want to ask you, what you suggest.
I have 3 different patient groups, only the steady state data, 10/10/13 (total of 33) arrays and the challenge is to classify the groups by the expression of all genes on the hgu133a chip. 
The named rule-based method found for each group genes, which explain a classification for each sample to one of the groups. 
Are there packages/method you can suggest? I guess PAMR works not so good for all genes on the chip, right?
Would be amazing if you can tell me your opinion.
All the best and thanks
Peter
