State-Stage representation of significantly selected genes using BSM. State-Stages are represented as active=1 in red, inactive=−1 in blue, or uncertain=0 in gray. Stages are indicated. Samples are shown in columns whereas genes are ordered by stage-state profile in vertical. Expression values ranges from 0 to 1 corresponding to various levels of colors from green to black then to red. Rank given by SAM is shown for comparison (black represents ranks from 1 to 215, dark gray to 500, light gray to 1000, and white >1000).
