Hi Bing,

Thanks for pointing this out.

We just entered this issue as Bug # 1639 in the BugTracker

and committed a fix into the CVS repository.

We added Vector<> and CovariantVectors for 5,6 and 7

Please update your CVS checkout and let us know if
that works for you, or you need additional dimension.

Please not that we will be adding support for Tensor
pixel type to ITK in the very near future. In particular
Gordon Kindlman is adding support to the NRRD file format
for facilitating to read and write DTI images.

You may find interesting to look at the DTI discussions
at the NAMIC Wiki page:
