Comp-het Data for "CryoBench: Diverse and challenging datasets for the heterogeneity problem in cryo-EM"

Synthetic cryo-EM datasets with simulated compositional heterogeneity and their ground truth atomic models, density maps, poses, labels, mask, and consensus volume:

Ribosembly: 335,240 particle images (128x128, 6A/pix) containing 16 bacterial ribosome assembly states from "Cryo-em captures early ribosome assembly in action" from Qin et al. (2023)

Tomotwin-100: 100k particle images (128x128, 9A/pix) containing a mixture of 100 different biomolecular complexes from "Tomotwin: generalized 3d localization of macromolecules in cryo-electron tomograms with structural data mining" from Rice et al. (2023)
