== Abstract ==

Cryogenic electron microscopy maps are valuable for determining macromolecule structures. A proper quality
assessment method is essential for cryo-EM map selection or revision. This article presents DeepQs, a novel
approach to estimate local quality for 3D cryo-EM density maps, using a deep-learning algorithm based on mapmodel
fit score. DeepQs is a parameter-free method for users and incorporates structural information between
map and its related atomic model into well-trained models by deep learning. More specifically, the DeepQs
approach leverages the interplay between map and atomic model through predefined map-model fit score, Qscore.
DeepQs can get close results to the ground truth map-model fit scores with only cryo-EM map as input. In
experiments, DeepQs demonstrates the lowest root mean square error with standard method Fourier shell correlation
metric and high correlation with map-model fit score, Q-score, when compared with other local quality
estimation methods in high-resolution dataset (<=5 Å). DeepQs can also be applied to evaluate the quality of the
post-processed maps. In both cases, DeepQs runs faster by using GPU acceleration. Our program is available at htt
