Issue downloading data from OneDrive (HCP FIB 1.25-mm MNI space)

[Isaac L.]

Dear Dr. Yeh,

My name is Isaac Levy and I'm a first year PhD student in the UVA School of Data Science working with Dr. Javier Rasero. 

I'm reaching out because I've been having some issues downloading the HCP FIB files from OneDrive. When I try to download them, the downloaded ZIP has been corrupted. I've attached a screenshot showing an example of the error. I've tried across multiple days and machines (Linux and MacOS), and the error has persisted. I've been able to download and process individual files, but whenever I try to download the whole set, it fails. If you have any advice or troubleshooting tips to be able to download these files I would greatly appreciate it.

Thank you in advance for your assistance.

Sincerely,
Isaac

You can use DSI Studio to download the data from Fiber Data Hub.

The python example to download data can also be found at brain.labsolver.org

Best regards

Frank

Thank you! Am I correct in assuming that the *.qsdr.fz files correspond to the FIB 1.25-mm MNI space files?

Additionally, is the Docker version of DSI Studio compatible with GPUs or only CPUs?

Thank you so much for your help!

It could be any resolution, not necessarily 1.25mm

GPU version.

Thank you for the clarification.

A couple follow-up questions:

1. I'm hoping to use the connectivity matrix to explore structural-functional coupling. For this purpose, would you recommend using 'pass' or 'end' for the --connectivity_value parameter?
2. The GUI instructions for connectivity matrices say that whole brain tracking should use at least 1,000,000 tracks; for CLI implementation, does this correspond to the --tract_count parameter?

Thank you very much,

Isaac

pass

Yes, but whole brain connectivities matrices are usually not very meaningful. I would suggest using autotract to map pathway first before getting connectivity matrices.

Just my two cents,

Frank
