Quality analysis of fragment libraries on all targets of CASP13 FM, CASP13 TBM and CAMEO test sets. a and b Fragment libraries constructed by NNMake (blue), Flib-Coevo (green) and DeepFragLib (red) were evaluated using precision (a) and coverage (b) at a series of RMSD thresholds. c–f Fragment libraries were evaluated using fragment level metrics for seven structural properties, i.e., the accuracy of fragment secondary structure, the error of torsion angles, ϕ, ψ, the error of backbone angles, θ, τ and the error of C_α − C_α distances and C_β − C_β distances. See Additional file 1: Figures S1–S3 for performance on respective test sets
