Q. Chen et al., “A large-scale curated and filterable dataset for cryo-EM foundation model pre-training,” Scientific Data, vol. 12, no. 1, p. 960, 2025.

== Abstract ==

Cryo-electron microscopy (cryo-EM) is a transformative imaging technology that enables near-atomic
resolution 3D reconstruction of target biomolecule, playing a critical role in structural biology and drug
discovery. Cryo-EM faces significant challenges due to its extremely low signal-to-noise ratio (SNR)
where the complexity of data processing becomes particularly pronounced. To address this challenge,
foundation models have shown great potential in other biological imaging domains. However, their
application in cryo-EM has been limited by the lack of large-scale, high-quality datasets. To fill this
gap, we introduce CryoCRAB, the first large-scale dataset for cryo-EM foundation models. CryoCRAB
includes 746 proteins, comprising 152,385 sets of raw movie frames (116.8 TB in total). To tackle the
high-noise nature of cryo-EM data, each movie is split into odd and even frames to generate paired
micrographs for denoising tasks. The dataset is stored in HDF5 chunked format, significantly improving
random sampling efficiency and training speed. CryoCRAB offers diverse data support for cryo-EM
foundation models, enabling advancements in image denoising and general-purpose feature extraction
for downstream tasks.
