[slicer-users] Converting from DWI to DTI

Actually I needed it in that format in order to change its resolution from (1x1x3) to (1x1x1). I found this TVResample module in DTI Toolkit that requires the DTI volume to be in *.nii.gz.
But can Slicer change the resolution without having to resort to that tool? And if it does, does it do the interpolation, or does it simply downsample?
Thanks,

Mmmmm
that does not have an easy answer I guess. That export feature is not yet implemented. What tools do you want to interact with?

Now how do I convert from a DTI that is in (*.nhdr  & *.raw.gz) format to a DTI that is in *.nii.gz format?
Thanks

Hi!
On the Diffusion menu -> Utilities there is one called Diffusion Tensor Estimation.
You can find all the details regarding the process in:http://www.slicer.org/slicerWiki/index.php/Modules:DiffusionMRIWelcome-Documentation-3.6
Happy to helpDemian
