3.2.23 B-Spline Grid Size

<BS_EPI_parameters></BS_EPI_parameters>

  • 5

This value determines the grid size of the bspline registration. The border size is set by default to a value of '3'. The final grid size is then (BS_EPI_parameters value)+3. The exact value to choose for this tag is not straight forward and will likely take some experimentation based on your specific data. However, values between 5 and 10 are generally best for this application.

This tag will only take effect if <bspline_EPI_correction> is 'on'.
