🧬 How to use DeepEMhancer Online

Use DeepEMhancer online for cryo-EM map post-processing and local-detail enhancement.

DeepEMhancer is a cryo-EM volume post-processing model designed to improve the interpretability of raw experimental maps. The paper argues that standard global B-factor sharpening misses an important reality of cryo-EM reconstruction: local map quality is heterogeneous, so a useful post-processing method must enhance detail and suppress noise in a locally adaptive way.

On Neurosnap, researchers upload a Density Map and choose the appropriate Model variant for the resolution regime and aggressiveness of cleanup they want. The service fits naturally before de novo model building, manual tracing, or refinement against a difficult map.

How DeepEMhancer Works

DeepEMhancer is trained on paired experimental maps and target maps sharpened with the help of their corresponding atomic models. As a result, it learns to perform masking-like and sharpening-like operations in a single step without requiring the user to provide a model at inference time. The paper reports improved local map quality, lower noise, and more detailed volumes on a held-out test set, including a SARS-CoV-2 RNA polymerase example.

On Neurosnap, tightTarget is the most aggressive cleanup option, wideTarget is more permissive when relevant density may otherwise be removed, and highRes is designed for maps where finer detail should be preserved. Researchers typically inspect the enhanced volume first, then decide whether it is ready for automated model building or whether additional reconstruction work is still warranted.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools.
