Comparison of the clustering results in the reduced space and in the original space (I). (a) The 20th cluster of K-means in the 7-dimensional space from the SC-MDS method. 45.5% of the genes in this cluster are annotated cell cycle functions. (b) The 59th cluster of K-means in the original 23-dimensional space. 40% of the genes in this cluster are annotated cell cycle functions. The blue lines are gene expression profiles and the red line indicates the average of these expression profiles.
