Walk-through connectomeDB
This walk-through tutorial shows how to obtain the subjects in a project of the ConnecotmeDB It is assumed that you have a working installation of datalad-xnat and you have accepted the data user agreement in connectomeDB.
Create a Datalad dataset. Here we'll call the dataset hcp
datalad create hcp
Move into the hcp dataset.
cd hcp
Initialize XNAT to track ConnectomeDB, and list all the projects in ConnectomeDB.We will use the project WU_L1A_Subj.
datalad xnat-init https://db.humanconnectome.org --project WU_L1A_Subj
If a dataset was already initialized before, you will need to force the initialization.
datalad xnat-init https://db.humanconnectome.org --project MGH_DIFF --force
Obtain all subjects within the project.
datalad xnat-update
Download all data that belongs to a subject, here subject ConnectomeDB_S01439. Make sure that you have enough free space on your disk.
datalad xnat-update -s ConnectomeDB_S01439
Now the data should start to download.
