Fig 8. Fragment geometry subject to cutoffs.

Midpoint distance: between the C_α atoms of the middle residues of two fragments; overlap distance: between the C_α atoms of the residues before and after the overlapping residues; overlap pair distance: between the corresponding N, C_α, C_β, and C atoms of the three overlapping residues; overlap angle: formed by the vectors from the N atom of the first overlapping residue to the C atom of the third overlapping residue.
