Niak for reading non-linear transformations
Hi all,
I'm encountering a problem when using niak to read a non-linear transformation from 'minctracc'. 'mincinfo' correctly shows that the grid transformation has 4 dimensions (3D position + vector for each grid point), but using 'niak_read_vol' yields a single 3D volume (just one direction of the vector at each grid point). I'd like to be able to open the non-linear transformation, manipulate it using MATLAB, then save it back to minc and use 'mincresample'. Any suggestions?
Best,
Phil
