(UNDER DEVELOPMENT): This gear attempts Voxel Based Morophometry using ANTs inspired by Seans paper https://www.sciencedirect.com/science/article/pii/S1053811921005498
Takes the isotropic hyperfine reconstructions that have been bias corrected (N4) and calculates volume estimates for white matter, grey matter & CSF by calculating Jacobian determinants.
- Requires matching to template used in recon
- Required brain mask from HD-BET (Could include conditional to run HD-BET if files not found)

No metadata currently created by this gear
- Three dimensional structural image
This gear runs on BIDS-organized data. To have your data BIDS-ified, it is recommended that you run, in the following order:
- dcm2niix
- Level: Any
- file-metadata-importer
- Level: Any
- file-classifier
- Level: Any
This section provides a more detailed description of the gear, including not just WHAT it does, but HOW it works in flywheel
This gear is run at either the Subject
or the Session
level. It downloads the data
for that subject/session into the /flwyhweel/v0/work/bids
folder and then runs the
hyperfine-vbm
pipeline on it.
After the pipeline is run, the output folder is zipped and saved into the analysis container.
This section contains specifications on any input files that the gear may need

Description of workflow
- Upload data to container
- Prepare data by running the following gears:
- file metadata importer
- file classifier
- dcm2niix
- Run the ciso gear (Hyperfine triplane aquisitions)
- Run N4 bias correction gear
- Run HD-BET
- Run VBM
