class etspy.base.CommonStack(Signal2D)[source]

An abstract base class for tomography data.

Abstract

This class is intended to be subclassed (e.g. by TomoStack and RecStack) and should not be instantiated directly. Doing so will raise a NotImplementedError.

All arguments (other than tilts and shifts) are passed to the Signal2D constructor and should be used as documented for that method.

Constructors

CommonStack(data: ndarray | Signal2D, *args, **kwargs)[source]

Create an ETSpy signal instance.

Methods

plot(navigator: str = 'slider', *args, **kwargs)[source]

Override of plot function to set default HyperSpy navigator to ‘slider’.

change_data_type(dtype: str | dtype)[source]

Change the data type of a stack.

invert() → Self[source]

Create a copy of a Stack with inverted contrast levels.

normalize(width: int = 3) → Self[source]

Create a copy of a stack with normalized contrast levels.

save_raw(filename: str | Path | None = None) → Path[source]

Save Stack data as a .raw/.rpl file pair.

stats()[source]

Print some basic statistics about Stack data.

trans_stack(xshift: float = 0.0, yshift: float = 0.0, ...) → Self[source]

Create a copy of a Stack, transformed using the skimage Affine transform.
