EpiATLAS TE measurements
EpiATLAS histone peak files (hg38) had their peaks resized to 200bp and then were overlapped with TEs from repeatmaskers. For each subfamily the number of overlap was tallied for the count overlap metric. For each sample, an associated simulated random sample was generated. These samples were generated such that they matched the peak distribution of distances to TSS.
Enrichment calculations
The enrichments, observed-expected and fold change are calculated from the observed count, relative to the count obseved in the random samples. Thus, observed count - expected count and observed count / expected count respectively.
Uploaded samples comparisons
Uploaded samples are taken as is and overlapped to the TEs from repeatmasker (hg38). Enrichments are calculated relative to the expected counts from average counts of the random samples associated with the selected assay and Cell type (from the EpiATLAS)
If 'All' Cell category is selected, random baselines are calculated from the average of all cell categories combined.

TEExplorer
TEExplorer is a TE portal that simplifies TE consideration by providing an atlas of TE enrichment within the epigenome that can be explored through specific queries. The Atlas cover 6 histone marks, over 40 cell types from the IHEC EpiATLAS dataset. In addition the portal allows the analysis of TE overlap within user uploaded Bed files and straightforward comparison with the atlas' data.
TE Overview
Overview of TE family enrichement across cell types and histone marks. Select TE, Histone and Cell types of interest for more specific inquiry.
TE Subfamilies
Investigate the subfamilies of a specific TE family and their coverage or enrichment within a histone across cell types
Import
Upload your own hg38 bed file to and obtain the TE overlap, TE enrichment visualization and compare your data with the EpiATLAS dataset
