a
Encoding and tabular files for a Stejskal-Tanner sequence. A series of volumes (upper left) are labelled with index t (table, lower left). These are defined with a prototypical sequence (right), and scaled and rotated by indices s and (x,y,z) respectively (bottom left, bottom middle).
Structure of files within an aDWI-BIDS folder (additional files bounded in blue). The encoding file describes a prototypical sequence, which is allocated to acquisitions given in the tabular file. The tabular file in turn may describe perturbations to the prototypical sequence on a parameter by parameter basis. Perturbed sequences describe slices or volumes within the NIfTI (figure 2).
