HCP Preprocessing does not include running tractography, and wb_command
doesn't do tractography (it can do some specific manipulations of FSL
tractography outputs, though, including averaging over ROIs). There are
as-yet unsolved issues with tractography (gyral bias, where streamlines
prefer to
Hi Rakib,
My colleagues and I normally use the Freesurfer Aseg ROIs and the diffusion
data in the same T1w folder of the preprocessed HCP data to compute the
structural connectivity. The same Aseg ROIs in the MNI space can be used for
functional connectivity.
To use the HCP1200

ICA based analysis has specific problem. To name a component (ICs), we need
domain expert. Hence, comparative analysis between structural and functional
connectivity cannot be quantified. I want to use an atlas template that can
also be used for DTI based tractographic data. Do I
Hi,
See the “HCP1200 Parcellation+Timeseries+Netmats (PTN)” packages hosted at
https://db.humanconnectome.org/data/projects/HCP_1200
There are “soft parcellations” (ICA-based, and cortical only) computed at
dimensionalities of 15, 25, 50, 100, 200, and 300.
Cheers,

Hello,
I am a student of machine learning. I want to study structural and functional
brain connectivity from HCP data. Is there any way to get ROI based time series
and structural connectivity using wb_command ? I am not sure about which ROI
atlas should I use. I need suggestion for specific
