Figure 3From: GOurmet: A tool for quantitative comparison and visualization of gene expression profiles based on gene ontology (GO) distributionsGOurmet can cluster expression profiles from varying platforms, from different labs, and of different lengths. A) Three different hematopoietic stem cell (HSC) expression profiles (one generated from a subtracted library [16], two from different GeneChips in different labs [5,6]) all cluster most closely with each other (marked by arrowheads) than with any of the other progenitor or differentiated cell profiles. B) A parent gene list composed of every annotated gene on the Moe430V2.0 GeneChip was reduced in length 10-fold by random exclusion of 9 in 10 genes and 100-fold by exclusion of 99 in 100 genes. The reduced length versions of the original list still cluster with the parent (marked by arrowheads). [32]Back to article page
