In direct comparison of methylation for an individual oyster prior to and following heat shock approximately 10k differentially methylated features were identified as defined by >/= 1.8 difference. For all oysters a majority of the features (probe region) were hypomethylated. Specifically, for oysters #2, #4, and #6 the number of hypomethylated features was 7224, 6560, and 7645, respectively. Genome feature tracks (bedGraph) for each oysters are available: genome-feature-tracks/2014.07.02.2M_sig.bedGraph, genome-feature-tracks/2014.07.02.4M_sig.bedGraph, genome-feature-tracks/2014.07.02.6M_sig.bedGraph.   ![](./figures/igv-dmr-1.png)  ![](https://www.authorea.com/users/3858/articles/18000/master/file/figures/igv-dmr-1.png)  Figure - Screenshot of genome feature tracks showing differential methylation.  When only features were considered where at least 3 adjacent probes were also differentially methylated the number of features (adjacent probes merged) for oysters #2, #4, and #6 was 112, 58, and 62, respectively. A majority of these features were hypomethylated (108, 48, and 53, respectively) 

In order to examine regions that were differentially methylated across all three oysters, features were identified where there were at least 3 adjacent probes with significantly differentially methylated. A total of 111 features were identified as hypomethylated and 54 features as hypermethylated when differentially methylated probe with 100bp were merged.
