The following programs allow the calculation of 3-D maps from single particle cryo-EM images, determination of image orientation parameters, refinement of image orientation parameters, and other related utilities. Many of the programs requires the subroutine library "fspace_subsandfuncs_vII.f90" to be located in the same directory for installation.
These versions of the program allow use of the "gold standard" Fourier Shell Correlation to avoid over-refinement of maps and interpretation of maps at inappropriately high resolution.
