Order in Schaefer 2018 100-parcel atlas parcellation

Hello everybody,

I am working on source-based EEG connectivity, and when I use the .annot file of the Schaefer 2018 100-parcel atlas, I noticed that there is a difference between the order of the labels in .annot (or my code) and the original label ordering.
While mine started with ‘7Networks_LH_Cont_Cing_1-lh’ and the original order started with ‘7Networks_LH_Vis_1’.

Is there anybody having a similar issue or any idea ?

Thanks,
Pouya

Here is my code:

fsaverage_dir = fetch_fsaverage()

sub_dir = Path(fsaverage_dir).parent 
os.environ['SUBJECTS_DIR'] = str(sub_dir)

# Atlas selection
atlas_name = 'Schaefer2018_100Parcels_7Networks_order'

labels = mne.read_labels_from_annot('fsaverage', 
                                    parc=atlas_name, 
                                    hemi= 'both',
                                    subjects_dir=sub_dir
                                    )
# Exclude the Medial Wall
labels = [label for label in labels if 'Medial_Wall' not in label.name]

Does the different ordering cause a problem? If you have access to the original order (as it sounds like you do) then it should be possible to re-order the list of labels.
