dear SPM list,
here a quite silly question: how can one determine the correct voxel
size in a given MRI volume in SPM5, for example by using spm_vol.m
(like previously with SPM2). V.mat doesn't lead anymore to the
desired information., like in the past by computing :
myVox = abs([ V.mat( 1, 1) V.mat( 2, 2) V.mat( 3, 3) ]) ;
for example, i expect to deal with 2x2x2mm, but Y.mat instead gives:
-1.9945 -0.0499 -0.1399 70.8144
-0.0891 1.9090 0.5896 -63.5382
-0.1188 -0.5942 1.9060 -60.7934
0 0 0 1.0000
that's now after rotation i guess (as no mat files anymore). looked
through the codes and also in the archives - w/o prevail.
thanks in advance, bye,
pisti
