EpiDISH web server: Epigenetic Dissection of Intra-Sample-Heterogeneity with online GUI.

SUMMARY: It is well recognized that cell-type heterogeneity hampers the interpretation of Epigenome-Wide Association Studies (EWAS). Many tools have emerged to address this issue, including several R/Bioconductor packages that infer cell-type composition. Here we present a web application for cell-type deconvolution, which offers the functionality of our EpiDISH Bioconductor/R package in a user-friendly GUI environment. Users can upload their data to infer cell-type composition and differentially methylated cytosines in individual cell-types (DMCTs) for a range of different tissues. AVAILABILITY AND IMPLEMENTATION: EpiDISH web server is implemented with Shiny in R, and is freely available at https://www.biosino.org/EpiDISH/.
