Hi,
After generating dense connectivity maps (*.dconn.nii files) from the HCP DWI
data, we would like to use previous parcellations (e.g. Desikan-Killiany) to
assess the reproducibility across subjects. As the grayordinates vertices are
assumed to be anatomically-matched across subjects, then there should be a
single lookup table to convert from HCP grayordinates to a given parcellation,
correct?
If so, does anyone have this as a simple table?
If not, what is the easiest way to generate it?
I realise that I can print out a (apparently zero-based) lookup table of
Label_IDs and Label_Names by doing:
wb_command -file–information
100307/MNINonLinear/fsaverage_LR32k/100307.aparc.a2009s.32k_fs_LR.dlabel.nii
Which produces:
Name: 100307.aparc.a2009s.32k_fs_LR.dlabel.nii
Type: Connectivity - Dense Label
Structure: CortexLeft CortexRight
Data Size: 237.65 Kilobytes
Maps to Surface: true
Maps to Volume: false
Maps with LabelTable: true
Maps with Palette: false
Number of Maps: 1
Number of Rows: 59412
Number of Columns: 1
Volume Dim[0]: 0
Volume Dim[1]: 0
Volume Dim[2]: 0
Palette Type: None
CIFTI Dim[0]: 1
CIFTI Dim[1]: 59412
ALONG_ROW map type: LABELS
ALONG_COLUMN map type: BRAIN_MODELS
Has Volume Data: false
CortexLeft: 29696 out of 32492 vertices
CortexRight: 29716 out of 32492 vertices
Map Map Name

Label table for ALL maps
KEY NAME RED GREEN BLUE ALPHA

150 R_S_temporal_transverse 0.867 0.235 0.235 1.000
Also, the following command:
wb_command -nifti-information -print-matrix
100307/MNINonLinear/fsaverage_LR32k/100307.aparc.a2009s.32k_fs_LR.dlabel.nii
produces the Label_ID : Vertex_Number mapping (again apparently zero-based):
Row 0: 72
Row 1: 27
Row 2: 29
Row 3: 16
Row 4: 59
Row 5: 26
…
Row 59407: 113
Row 59408: 113
Row 59409: 113
Row 59410: 113
Row 59411: 113
Is this the correct data to use to create a (label_name : vertex_number) lookup
table?
Cheers,
