HMP DACC is the Human Microbiome Project's Data Analysis and Coordination Center. A major goal of the HMP is to look for correlations between changes in the microbiome and human health. The HMP DACC is the central repository for all HMP data. More information about the project can be found on the NIH Roadmap site at http://nihroadmap.nih.gov/hmp. The recent HMP meeting included discussion about using the HMP DACC, and as the roadmap initiative continues, more data will be available for the research community.
