How to get the (x,y,z) coordinates of the 116 Regions of interest of the Automated Anatomical Labeling (AAL) atlas

Do you want the coordinates for all the voxels in each of the regions or a representative coordinate for each region?

I want a representative coordinate for each region

Hi,
You may want to use this function: nilearn.plotting.find_parcellation_cut_coords - Nilearn

Representative “center” points can be found in lots of different ways. One problem with the commonly used center of mass is that it can lie outside the region. In AFNI, see 3dDepthMap and 3dCM -icent for ways to find an internal center.
