importAllenConnectome Loads connectome weights after downloading from python

Syntax

W = importAllenConnectome(sourceId, targetId, sourceHemi, targetHemi) [W,
sourceIdx, targetIdx] = importAllenConnectome(___)

Description

W = importAllenConnectome(sourceId, targetId, sourceHemi, targetHemi) loads the connectome weights for the specified source and target structure IDs and hemispheres.

[W, sourceIdx, targetIdx] = importAllenConnectome(_) also returns the voxel indices for the source and target masks in PIR orientation.

Examples

W = importAllenConnectome(184, 184, 2, 3);
W = importAllenConnectome(184, 184, 2, 2);
[W, sIdx, tIdx] = importAllenConnectome(184, 184, 2, 2);

Input Arguments

sourceId - source structure ID (numeric scalar) Allen structure ID for the source region.

targetId - target structure ID (numeric scalar) Allen structure ID for the target region.

sourceHemi - source hemisphere selector (3 (default) | 1 | 2) 1 for left, 2 for right, 3 for both hemispheres.

targetHemi - target hemisphere selector (3 (default) | 1 | 2) 1 for left, 2 for right, 3 for both hemispheres.

Output Arguments

W - connectome weight matrix (numeric array) Matrix of connection weights from source to target voxels.

sourceIdx - source voxel indices (numeric array) Indices of source voxels in PIR orientation.

targetIdx - target voxel indices (numeric array) Indices of target voxels in PIR orientation.
