Parkinson's Disease Datasets
Overview
Since anatomic MRI is presently not able to directly discern neuronal loss in Parkinson’s Disease (PD), studying the associated functional connectivity (FC) changes seems a promising approach toward developing non-invasive and non-radioactive neuroimaging markers for this disease. While several groups have reported such FC changes in PD, there are also significant discrepancies between studies. Investigating the reproducibility of PD-related FC changes on independent datasets is therefore of crucial importance.
The data are comprised of 20 PD patients and 20 age-matched controls in the Tao Wu dataset. Both sets contain T1 and resting-state scans.
Experimental Protocol
For the resting-state scan, subjects were instructed to close their eyes and think of nothing in particular without falling asleep.
Scan Parameters (Click here for scan parameters in BIDS format)
Parameter | Tao Wu | |
---|---|---|
T1-weighted scan | Sequence -------------- Repetition time (TR) -------------- Echo time (TE) -------------- Voxel size |
MPRAGE (IR method) -------------- 1100ms -------------- 3.39ms -------------- 1 x 1 x 1 mm |
Resting-state scan | Sequence -------------- Repetition time (TR) -------------- Echo time (TE) -------------- Voxel size -------------- Voxel size -------------- # of Volumes |
Echo planar -------------- 2s -------------- 40ms -------------- 90° -------------- 4 x 4 x 5 mm (64 x 64 matrix, 28 slices, field of view=256mm x 256mm) -------------- 239 (8 min) |
Additional Information
The Tao Wu data was re-hosted from https://fcp-indi.s3.amazonaws.com/data/Projects/INDI/umf_pd/taowu.tar.gz

The following instructions require a basic understanding of UNIX/LINUX command lines. Future portal functionality may include downloads directly from the web browser. Dataset download is currently enabled through DataLad.
Note: The conp-dataset
requires version >=0.12.5 of DataLad and version >=8.20200309 of git-annex.
To install DataLad on your system, please refer to the install section of the DataLad Handbook (installation via miniconda is recommended in order to obtain the latest version of DataLad).
1) Initiate the CONP dataset
To initiate the CONP dataset (conp-dataset
), run the following command in the directory where you want
CONP datasets to be installed:
datalad install https://github.com/CONP-PCNO/conp-dataset.git
2) Install the Taowu dataset
To install the dataset, go into the created conp-dataset directory and run
datalad install
on the dataset Taowu
:
cd conp-dataset
datalad install projects/Taowu
3) Download the Taowu dataset
Now that the DataLad dataset has been installed, go into the dataset directory under
projects/Taowu
.
cd projects/Taowu
Note that files visible in the dataset are symlinks and will need to be downloaded manually using the
datalad get
command in the dataset directory:
datalad get <filepath>
Note, if you run datalad get *
command, all the files present in the dataset directory will be
downloaded.
