In-depth comparison of SPACE2 and SPACE1 performance on the Cao et al. (2023) training set. SPACE1 with a 1.25 Å RMSD threshold (green) and SPACE2 (blue) as well as an adaptation of SPACE1 (light green) using the default agglomerative clustering algorithm of SPACE2 (complete linkage criterion, 1.25 Å RMSD threshold) and an adaptation of SPACE2 (light blue) using the default greedy clustering algorithm of SPACE1 (1.25 Å RMSD threshold) were evaluated on the complete data set (all). Additionally, SPACE2 and its adaptation were evaluated on a reduced dataset which only included the 2,140 antibodies successfully modeled by homology modeling (reduced set).
