Hi Tim, Great, thanks for your fast answer. Generating the dense connectome files works good.
However, I’m not quite sure about the content of the dense connectome files. As far as I understood it, it is the complete connectivity matrix on a voxel-based scale. Is this right? This would be exactly what I need. My question now would be: Which steps or tools are usually used to extract the information stored in the dense connectome files for further post-processing? It would be really great if you could just outline the steps roughly and the tools I could use to get the network. Is there maybe a Matlab library available which is able to read .dconn.nii files?

You should be able to generate them by running wb_command -cifti-correlate on a subject's rfMRI dtseries file.

After studying the documentation of the Q3 release, I’ve only found group average dense connectome files so far. I’d like to know if there are any connectivity matrices available for individual subjects with which I could generate the corresponding connectome networks. Do you provide this kind of data? Where could I find it? And if not, do you plan to include it in future releases? Thanks for your help in advance and my best regards, Jürgen _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org<mailto:HCP-Users@humanconnectome.org> http://lists.humanconnectome.org/mailman/listinfo/hcp-users _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
