Is there a way to determine (or specify) the correspondence between the vertices when a cifti is converted to a "fake nifti" vs. separated to giftis?
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?) If the reassignment is fixed, is it available somewhere? thanks, Jo -- Joset A.
