Enum FslLeftRightOrder 

pub enum FslLeftRightOrder {
    Radiological,
    Neurological,
}

How FSL stores an image’s left-right axis, which decides whether FSL flips it on reading (FslGetLeftRightOrder2, fslio.c; read_volume calls makeradiological()): an image whose sform (or, without one, qform) has a negative determinant is radiological and read as it is; one with a positive determinant is neurological and FSL reverses its x axis before bet2 sees it (and back when saving). The mesh is not symmetric, so the flip changes the mask.

Variants

Radiological

Negative determinant (or no orientation): processed as stored.

Neurological

Positive determinant: x reversed for processing, as FSL does.

Implementations

impl FslLeftRightOrder

pub fn from_affine(affine: Option<&[f64; 16]>) -> Self

From a voxel-to-world affine (row-major 4×4, the sform or else the qform the image was read with). None (no orientation) and a determinant within 1e-12 of 0 are radiological, as in FSL.
