Welcome to the official PyDesigner project!

---

PyDesigner was inspired by NYU's DESIGNER_ dMRI preprocessing pipeline to bring pre- and post- processing to every MRI imaging scientist. With PyDesigner, users are no longer confined to specific file types, operating systems, or complicated scripts just to extract DTI or DKI parameters – PyDesigner makes this easy, and you will love it!

⁠Notable Features

• 100% Python-based scripts
• Minimized package dependencies for small package footprint
• Preprocessing designed to boost SNR
• Accurate and fast DTI and DKI metrics via cutting-edge algorithms
• One-shot preprocessing to parameter extraction
• Cross-platform compatibility between Windows, Mac and Linux using Docker
• Highly flexible and easy to use
• Parallel processing for quicker preprocessing and parameterization
• Easy install with pip
• Input file-format agnostic – works with .nii, .nii.gz, .mif and dicoms
• Quality control metrics to evaluate data integrity – SNR graphs, outlier voxels, and head motion
• Uses the latest techniques from DTI/DKI/FBI literature
• Works with DTI, DKI, WMTI, FBI, or FBWM datasets
• Supports multi-TE dataset processing

We welcome all DTI/DKI researchers to evaluate this software and pass on their feedback or issues through the Issues_ page of this project’s GitHub repository. Additionally, you may join the M-AMA Slack channel_ for live support.

System Requirements Parallel processing in PyDesigner scales almost linearly with the nummber of CPU cores present. The application is also memory-intensive due to the number of parameter maps being computed.

Based on this evaluation, for processing a single DWI using PyDesigner, we recommend the following minimum system specifications:

• Ubuntu 18.04
• Intel i7-9700 or AMD Ryzen 1800X [8 cores]
• 16 GB RAM
• 12 GB free storage
• Nvidia CUDA-enabled GPU
