Additional file 2. Data from aligning CATH2.4 domains. NeamTM3to20NoEndContraction.mat Data from global RMSD and TM-align alignments of alpha carbon backbone curves. The maximal length of Reidemeister moves is varied from 3 to 20 and end-contractions are not allowed. Similar data for the smooth representation of the backbone curve are contained in NeamTMSmooth3to20NoEndContraction.mat and in NeamTMSmooth3to20EndContraction.matwhen allowing end-contractions of MaxLength=2/residues.
