Tissues used in Supporting Result: Human and mouse tissues from the paper Su AI, Wiltshire T, Batalov S, Lapp H et al. A gene atlas of the mouse and human protein-encoding transcriptomes. Proc Natl Acad Sci U S A 2004 Apr 20;101(16):6062-7 are downloaded from Gene Expression Ombinus: GDS594 and GDS592 .

Experiments from Gene Expression Omnibus (GEO): Experiments of two species human (homo sapiens) and mouse(mus musculus) in GEO are downloaded from their FTP site. Excluding all datasets which we could not positively identify the control sample leaving us with 3416 and 2991 mouse microarays from 535 and 641 mouse datasets. Here are the list of human and mouse datasets.
