AAL78 Parcellation

In osl-dynamics, this parcellation file is named atlas-AAL_nparc-78_space-MNI_res-8x8x8.nii.gz, however, this parcellation file was previously named aal_cortical_merged_8mm_stacked.nii.gz (both names will work).

This parcellation contains the cortical regions from the Automated Anatomical Labelling atlas.
