Hi Mateus,
I can't address your original problem with the NIfTI
orientation/rotation, but I did have a look at your volumes, and this
statement confuses me:
The histogram of my images (3D_original.nii and 3D_resliced.nii) shows
several noisy sharp peaks.
The attached captures show the histogr
Spikes in histograms like these can sometimes arise from quantization
noise due to taking integer valued intensities and dividing into an
integer number of bins.
See for example this paper:

Hi Donna,
Thanks for your help. I am sending you two histograms of 3D_resliced.nii:
(1) histogram_resliced_1.jpg is the same histogram you already sent to me;
(2) histogram_resliced_2.jpg is the histogram of 3D_resliced.nii after
resampling at 1x1x1mm with Caret.
We can see that the spikes dis
Hi Mateus,
I think I have the problem corrected and here is how 3D_original.nii
appears in Caret. If the images look good to you let me know which
operating system you are using and I will make an update available
for you to download. This problem only occurred if the X-axis was
not lef
