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.) WebAlp Kucukelbir and Hemant Tagare wrote a nifty program to estimate the variation in resolution throughout the map [KST14]. relion implements a wrapper to this program …
