What isn’t available is individual subject parcellations which you didn’t need 
anyway given your initial question> ;)

Hi Matt,

Ah!  Sorry, I didn't realise a 32k_fs_LR version was ready (I thought it was 
only available for the 449 subjects).

Will check it out.

Hi Tom,

Why not use the multi-modal parcellation? https://balsa.wustl.edu/file/show/3VLx

Thanks Matt!

We're using it to just coarsely chop up the surface to build phenotypes.  What 
atlas would you suggest that we can easily apply with wb_command 
-cifti-parcellate?

Hi Tom,

This is because FreeSurfer “fits” the aparc to each subject.  There is probably 
an atlas aparc somewhere inside FreeSurfer that wouldn’t have this property.  
That does raise the question of why you are using aparc instead of one of the 
more functionally relevant parcellations available in standard CIFTI space 
though.  Aparc is unlikely to follow task boundaries much at all.

Subject: [HCP-Users] Variation in aparc ROIs between subjects in 32k_fs_LR space

Hi folks,

Sorry if this is a naive question, but looking for a sanity check...

We're using the aparc segmentations to extract data from the task fMRI CIFTI 
files.  We believe that we're working in atlas space (32k_fs_LR), so we were 
surprised that, when we load two different subjects into wb_view, the aparc 
segmentations are different for different subjects.

See attached images of
    100206.aparc.32k_fs_LR.dlabel.nii &
    100307.aparc.32k_fs_LR.dlabel.nii
The regions are similar but differ slightly, with the white dot showing a 
particular bit of the surface that changes from one ROI to another between 
subjects.  I would have expected this if we were in native space, but not 
32k_fs_LR.  What am I missing?

Thanks in advance!

-Tom

PS: A similar question was asked on May 9, titled "about the D-K atlas" from 
[email protected]<mailto:[email protected]> but it hasn't been answered; oddly, 
while it is in my inbox I can't find it in the archive.
