Re: [HCP-Users] How can I convert subcortical nifti files to dlabel files?

2017-08-09 Thread Timothy Coalson 
If your "mycluster.nii" is in a different volume space than 222 MNI RPI
space, then it may not let you use it that way.  Compare the nifti header
against this file in the HCP pipelines, using fslhd or wb_command
-nifti-information -print-header:

global/templates/MNI152_T1_2mm.nii.gz

If it is different, then you will need to resample your label volume.

Dear Tim,
Thank you for your reply
I have made sure that I have the group .dconn file opened, and I can see that 
it is correctly opened because I can see connectivity when I click on any 
structure.
However, I still have the same problem: I do not see the option of "Show Cifti 
Connectivity" when I right-click the cluster of the dlabel file I have created 
(however, I can see the dlabel file in the "Labels" list of the "Features 
Toolbox").

These are the steps I followed to create the dlabel file; I imagine I did 
something wrong in these steps but I cannot figure out what:
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
The resulting dlabel file is "mycluster_labelStep2.dlabel.nii"

Thank you very much,
Xavier.

You need to have a dtseries (or dconn) file open before you can see any kind of 
connectivity.  If you only have the labels/rois open, how do you expect it to 
figure out connectivity information?

Note that we only have options for averaging things inside a label, the ROI

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.

2017-08-09 Thread Glasser, Matthew 
Indeed the conversion from FreeSurfer annot format to GIFTI label format using 
FreeSurfer’s mris_convert does not preserve the probabilities (instead coloring 
every vertex with non-zero probability as a label).  Really though, FreeSurfer 
only provides those labels on individual subjects as a convenience.  If you 
want to compare the probabilistic areas in the HCP’s 32k_fs_LR space, you can 
use this file:

https://balsa.wustl.edu/file/show/n86p

Sorry that this is all a bit confusing.  It also doesn’t appear that we have 
released these probabilistic cytoarchitectonic maps in an especially obvious 
way in the BALSA database, so we can try to do this.

Dear all,

Could you provide a precise description on how the Brodmann area maps provided 
with the structural data (label files titled e.g. 
100307.L.BA.32k_fs_LR.label.gii) are obtained? I am currently working on the 
HCP500 release.

My understanding is that they are obtained from freesurfer's recon-all command, 
however this should provide probabilistic maps (according to 
https://surfer.nmr.mgh.harvard.edu/fswiki/BrodmannAreaMaps) and not the hard 
labels that we are given. I have been looking through the HCP documentation and 
publications and could not find a precise explanation.

Any help would be greatly appreciated.

Best wishes,

-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.

Dear HCP experts,
I have several subcortical nifti files, each containing one cluster. I would 
like to convert them to dlabel files, so that then I can use wb_view to see the 
functional connectivity from each of these clusters (using your group .dconn 
file).

How can I convert subcortical nifti files to dlabel files?
I have been exploring several wb_commands but I cannot figure it out.

Thank you very much,
Xavier.

Re: [HCP-Users] How can I convert subcortical nifti files to dlabel files?

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.

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:
