"WebDec 4, 2024 · For a visually improved map, try density modification (phenix.resolve for cryoem) as an alternative to sharpening. I wouldn’t report the resolution coming from this but visually it can increase 0.2-0.3A for areas with good density. I’ve seen it’s not so good with highly variable local resolution and tends to oversharpen lower res regions. " - Phenix cryoem refinement
