Table 2.

Average voxel F1 scores and residue Q3 accuracies of EMNUSS, Emap2sec and Haruspex on the middle-resolution experimental map test set for different secondary structure classes. Two different values of threshold were used in evaluation: 0.0 or author-recommended contour level. All the voxels or residues below this threshold were excluded from evaluation
