4.15. XYZ Topology Parser¶
New in version 0.9.1.
Reads an xyz file and pulls the atom information from it. Because xyz only has atom name information, all information about residues and segments won’t be populated.
4.15.1. Classes¶
-
class
MDAnalysis.topology.XYZParser.
XYZParser
(filename, universe=None, **kwargs)[source]¶ Parse a list of atoms from an XYZ file.

convert_forces_from_native
(force, inplace=True)¶ Conversion of forces array force from native to base units
Parameters: - force (array_like) – Forces to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input force is modified in place and also returned.
New in version 0.7.7.
-
convert_forces_to_native
(force, inplace=True)¶ Conversion of force array force from base to native units.
Parameters: - force (array_like) – Forces to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input force is modified in place and also returned.
New in version 0.7.7.
-
convert_pos_from_native
(x, inplace=True)¶ Conversion of coordinate array x from native units to base units.
Parameters: - x (array_like) – Positions to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input x is modified in place and also returned.
Changed in version 0.7.5: Keyword inplace can be set to
False
so that a modified copy is returned unless no conversion takes place, in which case the reference to the unmodified x is returned.
-
convert_pos_to_native
(x, inplace=True)¶ Conversion of coordinate array x from base units to native units.
Parameters: - x (array_like) – Positions to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input x is modified in place and also returned.
Changed in version 0.7.5: Keyword inplace can be set to
False
so that a modified copy is returned unless no conversion takes place, in which case the reference to the unmodified x is returned.
-
convert_time_from_native
(t, inplace=True)¶ Convert time t from native units to base units.
Parameters: - t (array_like) – Time values to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input t is modified in place and also returned (although note that scalar values t are passed by value in Python and hence an in-place modification has no effect on the caller.)
Changed in version 0.7.5: Keyword inplace can be set to
False
so that a modified copy is returned unless no conversion takes place, in which case the reference to the unmodified x is returned.
-
convert_time_to_native
(t, inplace=True)¶ Convert time t from base units to native units.
Parameters: - t (array_like) – Time values to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input t is modified in place and also returned. (Also note that scalar values t are passed by value in Python and hence an in-place modification has no effect on the caller.)
Changed in version 0.7.5: Keyword inplace can be set to
False
so that a modified copy is returned unless no conversion takes place, in which case the reference to the unmodified x is returned.
-
convert_velocities_from_native
(v, inplace=True)¶ Conversion of velocities array v from native to base units
Parameters: - v (array_like) – Velocities to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input v is modified in place and also returned.
New in version 0.7.5.
-
convert_velocities_to_native
(v, inplace=True)¶ Conversion of coordinate array v from base to native units
Parameters: - v (array_like) – Velocities to transform
- inplace (bool, optional) – Whether to modify the array inplace, overwriting previous data
Note
By default, the input v is modified in place and also returned.
New in version 0.7.5.
