maskR Applies a right hemisphere mask to a 3D volume

Syntax

V = maskR(V)
[V, mask] = maskR(V)

V = maskR(V) applies a right hemisphere mask to the input volume V, zeroing out voxels in the left hemisphere.

[V, mask] = maskR(V) also returns the logical mask used to select the right hemisphere.

V = maskR(rand(100,100,50));
[V, mask] = maskR(getAllenTemplate(100));

V - input volume (numeric array) 3D array to be masked.

V - masked volume (numeric array) Volume with left hemisphere voxels set to zero.

mask - logical mask (logical array) Logical array indicating right hemisphere voxels.
