WebOct 1, 2024 · CTFFIND3 does a good job estimating astigmatism and defocus more precisely than ACE, but it is more dependent on the starting value for defocus. Our strategy was to estimate the defocus first with ACE, then refine the defocus estimate using CTFFIND3 using the ACE value as a starting point.
