Understand which micrographs are worth processing and which are not worth the effort (e.g., broken, over-focused, mis-targeted, empty (vacuum or ice-only), cubic or non-vitreous ice, leopard skin, etc.)
Chapter 2: Data Curation
This chapter will help you to understand why input data curation is critical for cryoEM/ET, what happens when 'bad' data are not removed, and the appropriate parameters to ensure proper data 'cleaning.'
At the end of this chapter, you will:
- Understand why bad micrographs and bad particles must be removed ahead of 3D analysis
- How tomographic reconstructions are affected by improper fiducial alignment
