Hello everyone,

In order to resample the HCP-MMP1.0 parcellation, following steps were done and the new mesh is attached here.

1. download needed materials followed by suggestion below:
https://www.mail-archive.com/hcp-users@humanconnectome.org/msg06289.html

They are:
1.1 original mesh( Q1-Q6_RelatedParcellation210.CorticalAreas_dil_Final_Final_Areas_Group_Colors.32k_fs_LR.dlabel.nii) from BALSA: https://balsa.wustl.edu/WN56

1.2 download group standard 32K and 59K spheres for both hemispheres (Q1-Q6_RelatedParcellation210.L.sphere.32k_fs_LR.surf.gii; Q1-Q6_RelatedParcellation210.R.sphere.32k_fs_LR.surf.gii, L.sphere.59k_fs_LR.surf.gii & R.sphere.59k_fs_LR.surf.gii) from HCP Github: https://github.com/Washington-University/HCPpipelines/tree/master/global/templates/standard_mesh_atlases

2. using workbench, separate, resample and merge parcellation files:


wb_command -cifti-separate Q1-Q6_RelatedParcellation210.CorticalAreas_dil_Final_Final_Areas_Group_Colors.32k_fs_LR.dlabel.nii COLUMN -label CORTEX_LEFT Q1-Q6_RelatedParcellation210.L.CorticalAreas_dil_Final_Final_Areas_Group.32k_fs_LR.dlabel.gii
wb_command -cifti-separate Q1-Q6_RelatedParcellation210.CorticalAreas_dil_Final_Final_Areas_Group_Colors.32k_fs_LR.dlabel.nii COLUMN -label CORTEX_RIGHT Q1-Q6_RelatedParcellation210.R.CorticalAreas_dil_Final_Final_Areas_Group.32k_fs_LR.dlabel.gii
wb_command -label-resample Q1-Q6_RelatedParcellation210.L.CorticalAreas_dil_Final_Final_Areas_Group.32k_fs_LR.dlabel.gii Q1-Q6_RelatedParcellation210.L.sphere.32k_fs_LR.surf.gii L.sphere.59k_fs_LR.surf.gii BARYCENTRIC Q1-Q6_RelatedParcellation210.L.CorticalAreas_dil_Final_Final_Areas_Group.59k_fs_LR.dlabel.nii
wb_command -label-resample Q1-Q6_RelatedParcellation210.R.CorticalAreas_dil_Final_Final_Areas_Group.32k_fs_LR.dlabel.gii Q1-Q6_RelatedParcellation210.R.sphere.32k_fs_LR.surf.gii R.sphere.59k_fs_LR.surf.gii BARYCENTRIC Q1-Q6_RelatedParcellation210.R.CorticalAreas_dil_Final_Final_Areas_Group.59k_fs_LR.dlabel.nii
wb_command -cifti-create-label Q1-Q6_RelatedParcellation210.CorticalAreas_dil_Final_Final_Areas_Group_Colors.59k_fs_LR.dlabel.nii -left-label Q1-Q6_RelatedParcellation210.L.CorticalAreas_dil_Final_Final_Areas_Group.59k_fs_LR.dlabel.nii -right-label Q1-Q6_RelatedParcellation210.R.CorticalAreas_dil_Final_Final_Areas_Group.59k_fs_LR.dlabel.nii

NOTE: when doing merge, there's error for label-merge function for dlabel.nii file, therefore I changed the code to -cifti-create-label followed the suggestion from:
https://www.mail-archive.com/hcp-users@humanconnectome.org/msg03217.html

3.Pick up the new mesh: Q1-Q6_RelatedParcellation210.CorticalAreas_dil_Final_Final_Areas_Group_Colors.59k_fs_LR.dlabel.nii

4. Enjoy :)
