Expression profiles of top-scoring classes for drug treatments. Expression profiles of top-scoring classes (Sij > 1) for drug treatments: (a) Kanamycin, (b) Novobiocin, (c) Norfloxacin treatment of the wild-type strain. Classes are sorted from top to bottom in descending order of their scores. A row of pixels corresponds to a single gene expression profile; a blue color indicates relative decrease in transcript abundance, and a yellow color an increase.
