I am using matlab R2013a and spm8 to extract time courses from task experiment data. But following error is shown.Any solution? I can do it when I use another computer.

SPM computation : ...done Error with file nc005.img Error using spm_sample_vol Cant open image file.

Error in spm_get_data (line 44) Y(i,:) = spm_sample_vol(V(i),XYZ(1,:),XYZ(2,:),XYZ(3,:),0);

Error in spm_regions (line 138) y = spm_get_data(SPM.xY.VY,xSPM.XYZ(:,Q));
