Figure 2From: Partition decoupling for multi-gene analysis of gene expression profiling dataYeast cell cycle data. Expression levels for three oscillatory genes are shown. The method of cell cycle synchronization is shown as shapes: crosses denote elutriation-synchronized samples, while triangles denote CDC-28 synchronized samples. Cluster assignment for each sample is shown by color; above the diagonal, points are colored by k-means clustering, with poor correspondence between cluster (color) and synchronization protocol (shapes); below the diagonal, samples are colored by spectral clustering assignment, showing clusters that correspond to the synchronization protocol.Back to article page
