I'm running into a few problems with FDT. I've changed the default save
format to Analyze, but the headers do not appear to be writing correctly.
The data.img/hdr file created with eddy_correct has a x-voxel dimension
that is negative and if DTIfit is run on that file, the results are just an
empty volume. If I correct the header, DTIfit produces reasonable output,
but those files also have negative valued x dimensions.
The second issue is with eddy_correct. After running the correction on the
4-D data, the first slice on all images has missing data and the exact
amount missing differs across all the orientation and baseline images. It
almost looks like a rotation correction, but it only affects the bottom and
top slices. Could there be something that I am not doing properly?
The input image (s1_4D.img/hdr) and output image (data.img/hdr) can be found
