Thanks for this answer.<br>
By manipulation, I essentially mean reading a 6D .nii file,
extracting sub images, and writing them to .mhd format, hopefully
keeping the correct image information throughout the process. <br>
I'll see if my colleague can write to a more recent format, and
otherwise follow your advice about ReadUnknownImageType.<br>
<br>
Best,<br>
Cyril<br>

<div>What exactly do you mean my manipulation? There is an ITK
filter to change image information (<a moz-do-not-send="true"

but that only happens AFTER itk::ImageFileReader has done its
work.</div>

</div>
<div>Could you possibly try to get your collaborator to write a
few images using a latest variant of ITK (preferably version
matched with yours for consistency)? If not, then perhaps try
to read the information in the header using the example in <a

and then do comparisons between what you expect.</div>

<br>
I have recently started working with nifti files, to
collaborate with a colleague that uses this format. But
the itk::ImageFileReader does not correctly open the
nifti files I have (image size, offset and direction
matrix are wrong). I use a recent version of ITK (commit
from Feb 6 18:02:49 2017), but my colleague has his own
fork from nifti_reg, which is several years old.<br>
<br>
Two questions:<br>
- Does someone have experience in manipulating nifti
files from ITK, and if so, is it supposed to work fine ?<br>
- Have there been important modifications in the nifti
format in the last years, which the ITK reader would
have followed, and which could cause the issues I'm
seeing when opening old ones ?<br>
<br>
Best regards,<br>
Cyril<br>
