Dear Experts,

I am trying to update a program which used to use spm_sample_vol from
SPM96 to use the SPM2 equivalent routine.  I am getting the error "Bad
Image Dimensions" from spm_sample_vol and can't see where I'm going
wrong.  The following will illustrate what I am doing:

I='dynamic PET image name';
for i=1:num_frames
    P(i)=strcat(I,',',num2str(i));
end;
V=spm_vol(P);
% therefore V = 18x1 struct array created with spm_vol from an 18 frame
dynamic PET image
X=ones(1:V(1).dim(2));
Y=1:V(1).dim(2);
Z=X;
d=spm_sample_vol(V(1),X,Y,Z,0);

Can anyone else spot the obvious mistake?

Many thanks for any help.

Mark
