For example, wb_command -cifti-separate Parcels_LR.dtseries.nii COLUMN -metric CORTEX_LEFT out.func.gii produces a gifti with 32492 vertices, the first 10 of which have the values 1 2 3 4 5 6 7 0 8 9. Converting the same cifti via wb_command -cifti-convert -to-nifti Parcels_LR.dtseries.nii out.nii.gz -smaller-file gives a file of dimension 29706, 2, 1, 1. 29706*2 = 59412, which is also the number of rows in the text file that is given by wb_command -cifti-convert -to-text Parcels_LR.dtseries.nii out.txt. The first 10 values of these files is 1 2 3 4 5 6 7 8 9 10, different than the gifti. My guess is that the -cifti-convert output has fewer vertices than the -cifti-separate output because the medial wall is omitted. But is there a fixed ordering to how the 29706 cifti vertices fit into the 32492 gifti vertices? (Rephrased, is it something like the vertex in row 17,234 of the -cifti-convert -to-text file is always assigned to slot 10,222 of the -cifti-separate gifti file?)

Thus, -cifti-separate has to add in all the excluded voxels and vertices to its outputs, while -cifti-convert does not (however, -cifti-convert -to-nifti does have to work around the 32,767 limit on nifti-1 dimensions, which makes things interesting). The current commands and the 91k grayordinates space always have the vertices in ascending order. The 0 in your example is just a placeholder for missing data (medial wall), not a change in order. It is possible to make a cifti file with arbitrary order of vertices within a hemisphere (you can't interleave across hemispheres or structures in general), but wb_command doesn't have a way to make such a file from scratch (it will accept such files, if anyone makes them, but it strikes me as undesirable, to the point of thinking maybe the specification should have dictated the order). The -cifti-export-dense-mapping command will give you the index translation information for any dense cifti file. We may have released some cifti files that did not exclude the medial wall, and we have released some that have only surface data, and no volume data (~59k indices). All standard 91k grayordinate cifti files have the same index mapping (which is the definition of what makes them standard).

However then, what I do not understand is the file structure of the HCP data. The structural measures such as cortical thickness, curvature and myelin maps etc live in the MNINonLinear/fsaverage_LR32k rather than in the 'native space' directory. Can anyone shed light on this? It was perhaps not the best choice to put these measures inside the MNINonLinear folder, but for compatibility, that is where they will remain for now. They were computed in "T1w" space ("native volume space", not to be confused with "native mesh", which is an unrelated distinction). However, the myelin measure is based on a combination of imaging contrasts, and is not sensitive to changes in brain size, so it doesn't quite fit in the same class as curvature and thickness, which are measures of the cortical coordinates themselves.
