Table contains information on distribution of Affymetix probe sets between k-means clusters in skin and tongue.
Cluster: k-means cluster assignment.
Members: number of Affymetrix probe sets within the cluster.
Skin/tongue only (#): number of tissue specific probe sets.
Skin/tongue only (%): percentage of tissue specific probe sets.
Designation (level of change): name assigned to a group with indication of the amplitude of differential expression.
Pattern (%): percentage of the numbers of probe sets in each pattern against total numbers of probe sets.
*indicates clusters combined for later functional analysis
