📜 Data Use Policy
⚠️ **Important:**
Use of these data is subject to the PPMI Data Use Agreement (DUA). see data access here
Any researcher accessing or processing these data must have:
- Registered for access through https://www.ppmi-info.org
- Agreed to and been approved under the terms of the **PPMI DUA**
Unauthorized distribution, use outside of approved projects, or sharing with unapproved parties is strictly prohibited.
---
Each subdirectory contains:
- `*.nii.gz`: NIfTI image file
- `*.json`: Acquisition metadata
- (for DTI) `*.bval`, `*.bvec`: Diffusion encoding information
---
## 🧠 Modalities Included
| Modality | Description |
|---------------|---------------------------------------------------|
| `T1w` | High-resolution T1-weighted anatomical scan |
| `T2Flair` | T2-weighted FLAIR for white matter lesions |
| `DTI_LR/RL` | Diffusion tensor imaging with reverse PE |
| `rsfMRI_LR/RL`| Resting-state fMRI with reverse PE |
| `NM2DMT` | Neuromelanin-sensitive imaging, multiple echoes |
---
## 🧪 Suggested Usage
This dataset is suitable for:
- Diffusion tensor modeling and tractography
- Structural morphometry
- Resting-state functional connectivity
- Neuromelanin contrast analysis
If using this data in publications, cite PPMI appropriately and acknowledge the data access agreement.
---
## 🔧 Processing Notes
- Images are in NIfTI format, aligned to scanner space.
- Direction matrices and voxel spacing are encoded in metadata.
- DTI data includes `.bval` and `.bvec` files consistent with FSL/BIDS format.
- Dual phase encoding in rsfMRI/DTI can be used for susceptibility distortion correction.
