Dear Tim and Matt, Thank you very much for your reply. I tried -volume-label-import, followed by -cifti-create-label, followed by -cifti-all-labels-to-rois. After this, when I right-click the cluster in wb_view, I see the option "Show Data/Time Series Graph For Parcel [my cluster]" but I do not see the option "Show Cifti Connectivity For Parcel [my cluster]" (even though I can see this option for other parcels, such as the Yeo map). I have been trying different things but cannot figure it out.
Some extra information in case it is useful: My clusters are a group average registered to the HCP "S900_Average_T1w_restore.nii", so at this point I am not concerned about comparison across subjects. I would like to calculate functional connectivity from each of my subcortical clusters using your S900 .dconn file. My original nifti file with the right cerebellum cluster is called "mycluster.nii". I created the file "textforvolumelabelimport.txt" with the following text: CEREBELLUM_RIGHT 1 1 1 1 Then I did the following: wb_command -volume-label-import mycluster.nii textforvolumelabelimport.txt mycluster_label.nii wb_command -cifti-create-label mycluster_labelStep2.dlabel.nii -volume mycluster_label.nii mycluster_label.nii wb_command -cifti-all-labels-to-rois mycluster_labelStep2.dlabel.nii 1 mycluster_labelStep3.dscalar.nii When I right-click "mycluster_labelStep3.dscalar.nii" in wb_view, I can see the option of "Show Data/Time Series Graph" but not the option of "Show Cifti Connectivity". Thank you very much, Xavier. ________________________________ From: Timothy Coalson [tsc...@mst.edu] Sent: Tuesday, August 08, 2017 4:39 PM To: Xavier Guell Paradis Cc: hcp-users@humanconnectome.org Subject: Re: [HCP-Users] How can I convert subcortical nifti files to dlabel files? I'm assuming you want them to match a standard grayordinate space, so that they can be compared across subjects. The simple way that doesn't account for residual subject differences in subcortical locations is to first resample the data to the appropriate resolution/orientation MNI space (222 for the 91k grayordinates), then use -cifti-create-dense-from-template with the -volume-all option. The better but more involved way is to take the subject's subcortical structure labels from freesurfer, import them to workbench format with the names that -cifti-create-label specifies, use -cifti-create-label to make a subject-specific cifti file (you will also need to provide some dummy surface data for the next step to work), and then use -cifti-resample to use only the same-structure-overlap information, and dilate to fill in any holes if desired. We use this second method for fMRI data in the pipelines, see here: https://github.com/Washington-University/Pipelines/blob/master/fMRISurface/scripts/SubcorticalProcessing.sh#L40 Though that script actually only outputs a volume file, and therefore it doesn't bother with having surface data in those temporary cifti files.
