Wedge

class Wedge(angles=None, weights=None, tilt_axis=0, opening_axis=2, weight_type=None, frequency_cutoff=0.5, sampling_rate=1)

Bases: ComposableFilter

Create per-tilt wedge mask for tomographic data.

Attributes

Wedge.angles	Tilt angles in degrees.
Wedge.frequency_cutoff	Frequency cutoff for created mask.
Wedge.opening_axis	The projection axis, defaults to 2 (z).
Wedge.sampling_rate	The sampling rate, defaults to 1 Ångstrom / voxel.
Wedge.tilt_axis	Axis the plane is tilted over, defaults to 0 (x).
Wedge.weight_type	The type of weighting to apply, defaults to None.
Wedge.weights	The weights corresponding to each tilt angle.

Methods

Wedge.__call__([return_real_fourier])	This method provides the standard interface for creating of composable filter masks.
Wedge.from_file(filename, **kwargs)	Generate a Wedge instance by reading tilt angles and weights.
