Item Description
The method used to determine the final resolution
of the 3d reconstruction.
The Fourier Shell Correlation criterion as a measure of
resolution is based on the concept of splitting the (2D)
data set into two halves; averaging each and comparing them
using the Fourier Ring Correlation (FRC) technique.
