Dear SPM community,
I am trying to unwrap a phase image with the help of the unwrap function
of the fieldmap toolbox and get the following error message:
Error using ==> spm_conv_vol
Wrong sized dim.
Error in ==> spm_smooth at 111
spm_conv_vol(P,Q,x,y,z,-[i,j,k]);
Error in ==> pm_seed at 53
spm_smooth(P,svol,50);
Error in ==> bb_unwrap at 187
seed = pm_seed(angvar,mask,pxs);
When I display my image with spm, I get the following voxel size:
-0.513 0.513 3
I believe the negative voxel size is the problem. I really wonder why I
got a negative voxel size and how to fix it? I used the dicom import
function of SPM to import my DICOM files just as I usually did.
Any suggestions?
Benjamin
