check_backbone_continuity#

biotite.structure.check_backbone_continuity(array, min_len=1.2, max_len=1.8)[source]#

Check if the (peptide or phosphate) backbone atoms have non-reasonable distance to the next atom.

A large or very small distance is a very strong clue, that there is no bond between those atoms, therefore the chain is discontinued.

Parameters:
arrayAtomArray

The array to be checked.

min_len, max_lenfloat, optional

The interval in which the atom-atom distance is evaluated as bond.

Returns:
discontinuityndarray, dtype=int

Contains the indices of atoms after a discontinuity.
