Hierarchical clustering of differential expressed genes in the datasets.

<p>(A) Represents PTSD<sub>GSE860</sub> (yellow) vs Post-deploy PTSD<sub>GSE63878</sub> (red) condition (B) Represents PTSD<sub>GSE860</sub> (red) vs Pre-deploy PTSD<sub>GSE63878</sub> (orange) vs Post-deploy PTSD<sub>GSE63878</sub> (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.</p>
