Table 1 A spreadsheet representation of the investigation design graph shown in Figure 1.

From: A simple spreadsheet-based, MIAME-supportive format for microarray data: MAGE-TAB

  1. Each initial sample has a Sample ID (the first column in the spreadsheet) and Characteristics – Organism (genus and species) and OrganismPart (the second and third columns). The terms used to annotate the characteristics can be obtained from the MGED Ontology [26], another suitable source of controlled vocabulary terms, or provided as user defined terms. The fourth column gives a reference to a relevant protocol, while the fifth gives the IDs of the three hybridizations performed. The reference to the array design type (HG_U95A) is given as a hybridization property, which is followed by the data file names, a reference to the data normalization protocol and the normalized data file.
