WebJun 7, 2024 · 3D classification in Relion computationally 'purifies' your dataset, allowing you to further analyze a homogenous class This procedure can run on CTF-uncorrected or CTF-corrected data. Commonly, negative stain data will not be CTF corrected, but cryo-EM data will be CTF-corrected. 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.
