getAllenRMask Generates a right hemisphere mask for Allen volumes at a given resolution

Syntax

out = getAllenRMask(resolution)

Description

out = getAllenRMask(resolution) returns the logical mask, where voxels in the right hemisphere at the specified resolution are set to true and others to false.

Examples

mask = getAllenRMask(100);
mask = getAllenRMask(50);

Input Arguments

resolution - target resolution (numeric scalar) Resolution in microns for the Allen volume. Typical values are 25, 50, or 100.

Output Arguments

out - right hemisphere mask (logical 3D array) Logical array with true values for voxels in the right hemisphere.

Usage Notes

The mask is generated based on the third dimension (z) of the Allen volume, consistent with Allen mask definitions.
