🧠 DTI Processor with Eddy Correction

📤 Upload & Process 📊 Session Browser 📚 API Docs

About Viewing Results:

After processing completes, you can:

View individual maps using the buttons in the results section below
Access specialized interactive viewers (legacy data only) - Jensen Gap, Angular Entropy, ADC with full parameter controls
Browse sessions via the Session Browser to compute basic metrics (FA, MD, AD, RD, Color FA) or access session-based interactive viewers

Upload your DTI data for comprehensive processing with optional GPU-accelerated eddy correction:

MD: Model-based (from diffusion tensor)
Mean high b-value image: Model-free (mean of raw signals)
Angular Entropy (H_ang): Model-free
Generalized Anisotropy (R_aniso): Model-free

DWI NIfTI File:

B-Vectors File (.bvec):

B-Values File (.bval):

🔥 VERSION 2.0 - DWI JSON Sidecar (WITH DEBUG): ⭐ Recommended! Upload the .json file that came with your DWI data.
Automatically extracts: Phase Encoding Direction & Total Readout Time
Note: JSON values always take priority when uploaded. To use manual values instead, don't upload a JSON or clear the file selection.

3D FLAIR Image (Optional - for registration): If provided, can be used as registration target

Post-Contrast T1 Image (Optional - for registration): If provided, can be used as registration target

Registration Target: Choose which anatomic image to register diffusion maps to

Skip skull stripping (median_otsu) Check if the uploaded DWI volumes are already brain-masked.

MP-PCA Denoising Patch Radius: Range: 0-7 (default=0). 0=skip denoising. Higher values = stronger denoising but slower processing.

Run Eddy Current & Motion Correction (GPU) Uses FSL eddy_cuda11.0 for fast GPU-accelerated correction

Eddy Correction Parameters

Note: If you upload a JSON file above, these fields will auto-populate with extracted values (shown with green background). JSON values are always used when a JSON file is uploaded.

Phase Encoding Direction: Direction of phase encoding in acquisition

Total Readout Time (seconds): Check your protocol (typically 0.04-0.08s)

Replace outlier slices (repol)

Second Level Model: Movement model complexity
