RT Journal Article T1 Measuring local-directional resolution and local anisotropy in cryo-EM maps A1 Vilas, José Luis A1 Tagare, Hemant D. A1 Vargas Balbuena, Javier A1 Carazo, Jose María A1 Sorzano, Carlos Óscar S. AB The introduction of local resolution has enormously helped the understanding of cryo-EM maps. Still, for any given pixel it is a global, aggregated value, that makes impossible the individual analysis of the contribution of the different projection directions. We introduce MonoDir, a fully automatic, parameter-free method that, starting only from the final cryo-EM map, decomposes local resolution into the different projection directions, providing a detailed level of analysis of the final map. Many applications of directional local resolution are possible, and we concentrate here on map quality and validation.
