# Preprocessing resources

The versioned preprocessing implementation is maintained at:

https://github.com/PeirongLiL/MRI-PairedField

The workflow covers format and orientation standardisation, mask preparation, rigid and affine registration, reference-grid resampling, N4 bias-field correction and in-mask min-max normalisation. Source images, source-specific masks and required transforms are not bundled with this metadata directory.

For the DOI archive, a source-code snapshot corresponding to the dataset release should be stored separately from the image archives and identified by the applicable release version.
