% V        -  BrainNet_spm_vol structure

% hold     -  interpolation method for the resampling:
%              0         : Zero-order hold (nearest neighbour)
%              1         : First-order hold (trilinear interpolation)
%              2->127    : Higher order Lagrange (polynomial) interpolation
%                          using different holds (second-order upwards)
%              -127 - -1 : Different orders of sinc interpolation

% X        -  output image
