Connectome

[Óscar Peña-Nogales]

Hi all,

As I mentioned before, I am kind of new to both fMRI and C-PAC. And I would like to ask if it is possible to obtain a connectome matrix from the SCA analysis C-PAC does?

Best,

Óscar

Hi Oscar,

There are many different ways to go about calculating a connectome that are too numerous for me to list here.

However, C-PAC does actually automatically calculate the "ndmg" connectome graph outputs originally introduced by the Neurodata group at John Hopkins - these are generated when time-series extraction is enabled, and appear in the output directory as *_desc-ndmg_correlations.csv

More information on this particular connectome calculation:

If you want to replicate their preprocessing as well, you can simply run C-PAC using the "ndmg" preconfig.

Best,

Steve
