Fig. 1From: Accurate flexible refinement of atomic models against medium-resolution cryo-EM maps using damped dynamicsComparison between fitting results obtained with DDFF (a) i.e., using \(\sigma =R/(2\sqrt {3})\) and T determined by equating volumes at mean values, with those obtained with DDforge (b) whereby σ and T are simultaneously optimized by following a procedure depicted in Fig. 2Back to article page
