Reveal is our visual analytical approach to the challenges of eQTL data exploration and visualization. Reveal offers a graph-based visualization of associations between SNPs and gene expression. In addition we integrated a detailed genotype view relating summarized patient cohort genotypes with data from individual patients and statistical analyses. Although Reveal was designed for eQTL data, it also allows the exploration of GWAS data through the integration of the iHAT visualization system and several other traditional visualizations, such as Manhattan plots, and statistical methods as well as SNP effect prediction methods.
