The initial meeting of the  Electron Microscopy Validation Task Force (EM VTF) was held on September 28-29, 2010.   Twenty highly regarded EM scientists from around the world assembled at Rutgers University in New Brunswick NJ to consider possible validation standards for 3D maps and models produced by electron microscopy reconstruction methods. The 2-day workshop was  co-chaired by Richard Henderson (MRC, Cambridge) for map validation and Andrej Sali (UCSF) for model validation.  Initial recommendations are now published.  The full citation is:
