I have a DTI dataset (several, actually), which I have converted from
DICOM files using dcm2nii. While the DICOM images read as expected in
OSIRIX and other DICOM viewers, the NIFTI image does not. The number
of slices and slice/volume ordering is correct, but it looks like
there is a problem with the pixel encoding. fslhd shows that the
datatype is 4 with 16 bits per pixel. When I convert the NIFTI image
to ANALYZE using fslchfiletype (in order to read into another viewer),
the datatype changes to 16 with 32 bits per pixel. The images retain
their strange appearance. These are Philips Achieva (release 2.5)
images. I do not have this problem when converting from PAR/REC, but
in these cases I cannot get the data in PAR/REC format.
Any help would be much appreciated!
