I am going to investigate enhancers in human heart tissue. Currently, I am using the VISTA Enhancer Browser to search for enhancers, but I am a little conserned due to lack of consensus of the suggested enhancer locations by the browser and displayed VISTA enhancers by UCSC Genome Browser. The elements do not overlap even though the data should be derived from the same studies and I use the hg19 genome for both browsers.
Have anybody faced similar problems? Alternatively, does anyone suggest other browsers/tools for finding location of enhancers regulating specific genes?
