  Direct B0 mapping sequences
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
  When the fieldmap is directly measured with a prescribed sequence (such as
  :abbr:`SE (spiral echo)`), we only need to calculate the corresponding B-Spline
  coefficients to adapt the fieldmap to the TOPUP tool.
  This procedure is described with more detail `here <https://cni.stanford.edu/\
  wiki/GE_Processing#Fieldmaps>`__.
  
  This corresponds to the section 8.9.3 --fieldmap image (and one magnitude image)--
  of the BIDS specification.
