Giles39 Parcellation

In osl-dynamics, this parcellation file is named atlas-Giles_nparc-39_space-MNI_res-8x8x8.nii.gz, however, this parcellation file was previously named fmri_d100_parcellation_with_PCC_tighterMay15_v2_8mm.nii.gz (both names will work).

This is a modified version of the original Giles parcellation to include the PCC.

This parcellation was used in Quinn et al. (2018).
