Hierarchical clustering of differential expressed genes in the datasets.

(A) Represents PTSDGSE860 (yellow) vs Post-deploy PTSDGSE63878 (red) condition (B) Represents PTSDGSE860 (red) vs Pre-deploy PTSDGSE63878 (orange) vs Post-deploy PTSDGSE63878 (red) condition. All the probes were clustered based on normalized signal intensity ratios. Each row represented a single gene; each column represents the samples in each condition with an average linkage of expression.
