Dear FSL group,
I recently encountered a change in behavior of fslswapdim. The following command:
fslswapdim input -x y z input_xflip
normally does a real x-flip, in a way that the data is reorganized in the nii file, but the header remains unchanged.
On Ubuntu, 16.04. LTS, FSL 6's fslswapdim now changes the header, too, so that an x-flip has no effect anymore. Does anybody see the same or is this a local, platform-dependent bug or, even worse, a new and wanted behavior?
Just to bring to mind again, a real x-flip of the data is sometimes necessary, as there are many tools out there, that ignore header information and the take the nifti file as it is. fslswapdim was a reliable way for me to arrange voxel data arbitrarily - up to now…
Thanks in advance,
Martin
