LAFTER yields xFSCs approaching Cref in contrast to other local filters. Regions of EMD-3954 representing protein structure and DNA structure are shown from globally filtered (A), LAFTER filtered (B), RELION local filtered (C) and BLOCFILT filtered (D) maps. One notable benefit of LAFTER is the recovery of stronger phosphate densities within the DNA backbone than are visible under the other local filtering approaches. Curves for the half-set FSC, C_ref and Filter-Sum xFSC in each case are adjacent and described in the key.
