== Abstract ==&lt;br /&gt;
&lt;br /&gt;
Cryogenic electron microscopy (cryo-EM) has transformed structural biology by enabling near atomic resolution&lt;br /&gt;
imaging of macromolecular complexes. However, cryo-EM density maps suffer from intrinsic noise arising from&lt;br /&gt;
structural sources, shot noise, and digital recording, which complicates accurate model building. While various&lt;br /&gt;
methods for denoising cryo-EM density maps exist, there is a lack of standardized datasets for benchmarking&lt;br /&gt;
artificial intelligence (AI) approaches. Here, we present an open-source dataset for cryo-EM density map denoising&lt;br /&gt;
comprising 650 high-resolution (1-4 Å) experimental maps paired with three types of generated label maps:&lt;br /&gt;
regression maps capturing idealized density distributions, binary classification maps distinguishing structural&lt;br /&gt;
elements from background, and atom-type classification maps. Each map is standardized to 1 Å voxel size and&lt;br /&gt;
validated through Fourier Shell Correlation analysis, demonstrating substantial resolution improvements in label&lt;br /&gt;
maps compared to experimental maps. This resource bridges the gap between structural biology and artificial&lt;br /&gt;
intelligence communities, allowing researchers to develop and benchmark innovative methods for enhancing&lt;br /&gt;
cryo-EM density maps.&lt;br /&gt;
