  • Description

    a tool for assessing how well atomic model features are resolved in cryoEM maps. A fitted model is used in the analysis. A Q-score is calculated for each atom in the model. Q-scores can then be used to visualize how well each residue/atom is resolved and averaged to represent the entire model/map.

  • Usage Notes

    MapQ is a plugin for Chimera.
