An example of an investigation design graph for a simple one-channel array experiment. Three samples are used: liver, kidney, and brain. Labeled RNA extracts from each sample are hybridized on an array (type HG_U95A). The RNA extraction and labeling are described in the Material processing protocol, P-XMPL-1. Raw data files (Data1.cel, Data2.cel and Data3.cel) are obtained, and then normalized and summarized as described in the Normalization protocol, P-XMPL-2, generating the file FGDM.txt.
