Parcel centroids from a label volume — parcel_centroids_from_labels • fmrigpca

Computes centroid coordinates (i,j,k) for labeled parcels in a NeuroVol label image. Labels with value 0 are ignored.

Usage

parcel_centroids_from_labels(parc_vol, labels = NULL)

Arguments

parc_vol: NeuroVol of parcel labels (integer; 0 treated as background).
labels: Optional integer vector of labels to include.

Value

A list with coords (P x 3 matrix) and labels (length P).

Details

For each parcel label, voxel coordinates are averaged to obtain a centroid. Optionally restrict to a provided vector of labels.
