From: Expression cartography of human tissues using self organizing maps
Single gene (left panels) and metagene (right panels) correlation analysis of human tissues using the 1000/100 most strongly regulated genes/metagenes: (a) Pairwise Correlation Map (PCM); (b) Frequency distributions of correlation coefficients for all intra- and inter-tissue category pairings and (c) for pairings of intra-nervous tissue pairings and for pairings between nervous and all other tissues. Note that the metagenes produce the stronger contrast of the PCM clusters due to the sharper and better resolved distributions.
