Dear SPM experts,
I intend to look at the T1/T2 ratio using some T1-W and T2-W structural MRI images. To achieve this, I tried to co-register T2W to T1W images using normalized mutual information with SPM12. However, the quality of output images obtained from this co-registration is not valid and unusable for further analysis.
In my case, there are T1W (0.94x0.94x1 mm) and T2W (0.45x0.45x4 mm) images with specified voxel dimensions within brackets. The output images from the coregistration were absolutely fine. However, T1W (0.94x0.94x0.66 mm) and T2W (0.45x0.45x0.32 mm) images with different voxel dimensions shows up the warning message as given below. Please see the screenshot of the coregistered output image attached. I wonder whether the T1W and T2W images with latter voxel dimensions are suitable for coregistration? Can anyone provide me some suggestions please?
thanks,
best,
Varun
