Function: squareROI()

function squareROI(
   vol, 
   centroid, 
   surround, 
   fixDim?, 
   fill?, 
   nonzero?): ROIVolWindow;

Defined in: src/roi/ROI_factories.ts:190

Creates a square ROI with a fixed dimension (e.g., z-dimension). This creates a 2D square in the plane perpendicular to the fixed dimension.

Parameters

vol

NeuroVol

The NeuroVol representing the volume

centroid

number[]

The center voxel coordinates [i, j, k]

surround

number

Number of voxels around the center voxel

fixDim?

number = 2

The dimension to fix (0 for x, 1 for y, 2 for z)

fill?

number = 1

Optional value to assign to the data slot. Defaults to 1

nonzero?

boolean = false

If true, only include voxels with non-zero values

Returns

ROIVolWindow

An ROIVolWindow representing the square ROI
