WebCryo-EM maps can be improved by methods such as sharpening/blurring and density modification. Sharpening can reveal the high-resolution details concealed in the cryo-EM … WebThe default way of calculating FSCs in the 3D auto-refinement is without masking the (gold-standard) half-maps, which systematically under-estimates the resolution during refinement. This is remediated by calculating phase-randomised solvent-corrected FSC curves at every iteration, and this generally leads to a noticeable improvement in resolution.)
