                                      TorsionAnglesCollection

Describes a collection of torsion angles. Provides 1-based list-like access.

Instance Methods
__init__(self, items=None, start=1) x.__init__(...) initializes x; see help(type(x)) for signature | source code
__repr__(self) repr(x) | source code
float |
rmsd(self, other) Calculate the Circular RSMD against another TorsionAnglesCollection. | source code
update(self, angles) | source code
Inherited from `core.CollectionContainer`: `append` Inherited from `core.BaseCollectionContainer`: `__bool__`, `__contains__`, `__getitem__`, `__iter__`, `__len__`, `__nonzero__` Inherited from `object`: `__delattr__`, `__format__`, `__getattribute__`, `__hash__`, `__new__`, `__reduce__`, `__reduce_ex__`, `__setattr__`, `__sizeof__`, `__str__`, `__subclasshook__`

Properties
list | omega List of all omega angles
list | phi List of all phi angles
list | psi List of all psi angles

Method Details

### __init__(self, items=None, start=1) (Constructor) | source code
x.__init__(...) initializes x; see help(type(x)) for signature Parameters: `items` (list) - an initialization list of TorsionAngles Overrides: object.__init__ (inherited documentation)

### __repr__(self) (Representation operator) | source code
repr(x) Overrides: object.__repr__ (inherited documentation)

### rmsd(self, other) | source code
Calculate the Circular RSMD against another TorsionAnglesCollection. Parameters: `other` (TorsionAnglesCollection) - subject (right-hand-term) Returns: float RMSD based on torsion angles Raises: `Broken3DStructureError` - on discontinuous torsion angle collections (phi and psi values are still allowed to be absent at the termini) `ValueError` - on mismatching torsion angles collection lengths
