BundleParc-flow

BundleParc-flow is a workflow for parcellating white matter bundles from diffusion MRI using BundleParc and nextflow.

Requirements

• Nextflow
• Docker or Singularity

Usage

nextflow run scil-vital/BundleParc-flow -profile <docker/singularity>,gpu --input <INPUT> --outdir <OUTDIR> 

See USAGE for more instructions on how to run the workflow or use --help for more details.

Note: you will most likely have to have internet access when running for the first time to pull the code, docker containers and model weights. Have a question ? Found a problem ? Please open an issue or contact me at antoine (dot) theberge (at) usherbrooke (dot) ca.

Bundles

Bundle defintions follow TractSeg's, without the whole corpus callosum. However it is still represented in 7 subparts which should be coherent between their parcellations.

For completeness the bundle definitions are listed below
