Your task is to find differentially expressed genes using two conditions of your choice $($for each

condition there should be at least $5$ samples$).$ For instance, you might want to find differentially

expressed genes in a tumor $($called target or case$)$ taking normal tissue as reference $($called also control$).$

DATA

Find expression data from a study using Affymetrix $($one$-$color$)$ array for two conditions of your choice.

For each condition, there should be at least two independent samples. The raw data should be in CEL

file format. You may use following links to find raw data:
