In particular, if you are only tracking the parcels x parcels matrix, using
the 59k surfaces should make effectively no difference. They mostly exist
to try to capture the higher resolution fMRI data. Even if you were
capturing per-vertex tractography counts, the uncertainty in the

Are you wanting to view the files? You could probably translate the file into
a .dscalar.nii using matlab.

Thanks Tim, running cifti-transpose and separating on COLUMN solved both
issues. Is there a way to separate the different parcels that make up a
pdconn so that I can compare the connectivity maps between parcels?
Thanks,

Hi Reza,
Your interpretation of the timing is correct. The validation segment in
each movie scan was shifted by 40-200ms for the "v2" version. This was done
in order to make that final 83 second clip begin precisely at the start of
the next TR for all 4 movie sessions.
Given HRF variability,
I wanted to contrast the connectivity of the different parcels in order to
look for evidence of gradients in networks. I'll try it in matlab.

Also, if you literally want spatial gradient magnitude, you can run
-cifti-gradient on the correct dimension of the pdconn (or dpconn) file.

Each row or column (the shorter dimension) will be a dense map for connectivity
to a parcel.

You don't need matlab for that, -cifti-change-mapping will let you reset a
dimension to scalars. Depending on the input file, you may also need a
-cifti-transpose to get a dscalar.

If you just want to look at them first, you can load them into wb_view.
Depending on whether it is pdconn or dpconn (via a transpose), you will
either get a dense map when you click a parcel, or a parcellated map when
you click a vertex/voxel.
