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. WebMay 1, 2014 · Furthermore, CTFFIND3 is independent of any external programs or libraries, so it can be easily installed and used without the need for challenging setups. However, CTFFIND3 is not entirely automated as the user has to provide a range of spatial frequencies within which the goal function is evaluated.

Webyou can tweak the CTFFIND3-parameters in the corresponding _ctffind3.com file, and run the script again for a particular micrograph. Alternatively, if many models are wrong, you could also make a new STAR file with those, and then re-run the estimation of all of them by changing the CTFFIND3- parameters in the RELION GUI.
