First benchmarking

Finally it runs. Now with SerialEM we can collect up to 90 images per hour with 40 frames per image on K2 in counting mode. Many thanks to Jaap Brink and David Mastronade for their help with setting up and troubleshooting SerialEM. The microscope is very stable and the benchmarking is under way. The first data have been collected from GroEL .

EM images taken with GroEL sample leads to a reconstruction reaching 2.8 A resolution.
With 1.2 Å/pix the average resolution of reconstruction is 2.8 Å with  local resolution down to 2.7 Å. 
The obtained electron density is in agreement with the stated resolution.
