MRICloudRescale

Purpose. Rescale ASL and optional M0 NIfTI files by removing header scaling (scl_slope, scl_inter) so downstream math works in raw intensity units.

Behavior

  • For each {asl} (and optional M0), reads from rawdata/..., writes rescaled copy into the derivatives mirror with identical names.

  • Sets output dtype to float32 and clears scaling to 1/0.

Inputs

  • rawdata/<sub>/perf/{asl}.nii (and {M0}.nii if present)

Outputs

  • derivatives/<sub>/perf/{asl}.nii (and {M0}.nii) with rescaled data.

Configuration

  • None.
