Module: Extract Slices ()

Description:

This is an experimental module from the Xtra Library: https://xtras.amira-avizo.com.

This module allows extracting a set of slices from the input volume. It generates a volume as output. The set of slice numbers to be extracted can be randomly generated, or manually provided. The same set of slice numbers can be used to extract from a second dataset - typically, to extract slices from a grayscale and a label field.

Connections:

Data [required]
Input dataset from which slices will be extracted.

Ports:

Console

Opens the Python Script Object console of the module as the active console window.

Slice Selection

The total number of slices to be extracted is nb slices. The random selection is obtained by a random permutation of the slices, and extraction of the first ones. If nb intervals is more than 1, a similar process is applied for each slab of data, the slabs being of equal dimensions in the z directions.

List of Slices

• New Random List allows generating a new random list of slice numbers to be extracted, using the rules described in the Slice Selection port.
• Randomize Current List performs a random permutation on the current list.
• Clear clears the list.

Input List

List the slice indices to be extracted. This list is not saved when saving the project file, but it may be saved in a text file, and restored by copy-paste. You may also input manually the slice numbers you desired, using the same format with space separated integers within brackets.
