In jpellman/spmR: Statistical Parametric Mapping in R

Description

SPM: returns voxel values from a memory mapped image - a compiled routine

Usage

X = spm_sample_vol(V,x,y,z,hold);
[X,dX,dY,dZ] = spm_sample_vol(V,x,y,z,hold);
Similar to above, except that the derivatives in the three orthogonal
directions are also returned.

Arguments

V	a memory mapped image volume
x	matrix of x coordinates pixels
y	matrix of y coordinates pixels
z	matrix of z coordinates pixels
hold	sets the 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.
