The SOM analysis for two biological replication datasets of H3K4me3 in response to extended darkness. The ChIP-seq data in different conditions are mapped to a trained SOM map in PCSD, which represents a re-organizing genome through clustering genome segments based on multiple epigenetic signals. “Control - Dark” represents the result of subtracting signals under the dark treatment from signals under control condition. “Dark - Control” represents the result of subtracting signals under the control condition from signals under the dark treatment.
