Figure 11
Different reconstructions of protein GH168 using the magnitude-and-gradient algorithm. All images are plotted at a contour level of RMSD = 1, i.e. (Mean + 1 standard deviation), using ChimeraX. (a) The ground truth. All reconstructions are performed without a shrinkwrap support constraint. (b) $[q_{\rm {stop}} = 2,\eta = 10]$ , CC = 0.95. (c) $[q_{\rm {stop}} = 4,\eta = 10]$ , CC = 0.85. (d) $[q_{\rm {stop}} = 2,\eta = 1]$ , CC = 0.79.
