Figure 6From: Workflows for microarray data processing in the Kepler environmentOne output graph from AMDA workflow applied to NCBI GEO dataset GSE7181. One output of the Affymetrix gene expression workflow is displayed in Figure 5. This is a display of the file Data_norm_HeatMap.png, which is produced and stored by the workflow (see RESULTS). This is a heatmap representation of clustering of differentially expressed genes from six gene expression microarrays, each from a different line of brain tumor stem cells. The three adherent lines cluster together to the left; the three lines that grow as neurospheres cluster together to the right. Details of experimental methods and goals are found in [31] and [32] and heatmap generation methods details in [9].Back to article page
