Figure 1From: Sample phenotype clusters in high-density oligonucleotide microarray data sets are revealed using Isomap, a nonlinear algorithmHierarchical clustering of samples in the spinal cord injury data set. One hundred seventy rat high density oligonucleotide arrays were clustered with hierarchical clustering as described in Systems and Methods. The samples are annotated on time, location, and severity of the injury.Back to article page
