Request functional and structural connectivity matrices

[小明]

Hi,
Is there publicly available processed (1) time series data or (2)functional connection matrix data, which from rest fMRI.

and (3) structural connection matrix data from diffusion MRI data.

I find a data only include HCP 100 unrelated, I want more.
Thanks a lot.

db.humanconnectome.org has the resting state timeseries for about 1000 subjects in the "S1200" release (slightly over 1200 volunteers, some of which did not complete scanning, or where the scans had data quality issues).  There is also a group average functional connectivity matrix (click "open dataset", then look for "Group Average Functional Connectivity" on the right side of the Resources tab).

We have not released tractography results from the diffusion data, largely because of the gyral bias in the results of cortex-to-cortex tracking algorithms, and as far as I am aware, this bias has not yet been successfully resolved in new whole-brain algorithms.

Thank you.

I find two dataset:

1, "This database contains the connectivity matrices of the resting-state functional MRI scans that were collected in two databases of the Human Connectome Project, Young Adult and Aging. These matrices contain the functional connectivity between brain regions (here, several different brain atlases were used, leading to several different connectivity matrices for each subject).",  from-- Tijhuis, Floris Benjamin, Schepers, Minne, Centeno, Eduarda, Maciel, Bernardo de A.P.C., Douw, Linda, & Nobrega Santos, Fernando. (2022). Human Connectome Project resting-state fMRI Connectivity Matrices (Young Adult + Aging) [Data set]. Zenodo. https://doi.org/10.5281/zenodo.6770120

2,  This one include HCP 100 unrelated: Structural connectomes, Regional time series, Region volumes. https://github.com/DynamicsAndNeuralSystems/humanStructureFunction, from-- Fallon et al. (2020), Network Neuroscience. Timescales of spontaneous fMRI fluctuations relate to structural connectivity in the brain.

There, could we initiate a project to share the connection matrices, time series, morphological of regions, etc. that researchers have processed, for the benefit of researchers who lack computational resources such as HPC?

With the greatest respect.

The Data Use Terms you agree to when getting access to ConnectomeDB covers all usage of the data downloaded from there, including sharing derived results.  In essence, the answer is "your own IRB (or whoever is responsible for human-research ethics in your organization) should tell you how you can distribute your results, we don't want to stop you".  We negotiated with our own IRB to make our data use terms as permissive as we could.

For reference: https://www.humanconnectome.org/study/hcp-young-adult/document/wu-minn-hcp-consortium-open-access-data-use-terms

For those other papers you mention, the authors aren't in the HCP or CCF consortiums, and they may have applied additional restrictions in their use terms.  Ask them, not us.
