•  Integrated platform to support translational research
•  Initiated by Johnson & Johnson et Recombinant 7 years ago
•  Open-source since January 24th , 2012
•  Installed at HEGP Hospital, Paris since May, 2012
•  Today, driven and maintained by the tranSMART
http://transmartfoundation.org
Objectives :
1.  Integration of clinical, biological and ‘omics
data in one place – hypothesis free –
2.  Generation of hypothesis by Clinicians /
Researchers
