Hello,
I would like to apply a transformation to diffusion images (4D volume). Then I use Apply a transformation, but it add all the volumes (different directions for diffusion volumes) and it apply the transformation to the residual sum (the result is a 3D volume). Is it possible to apply a transformation to each 3D volume of a 4D volume.
To try this, I use also in converters "single files to volume series". But it only take my 4D diffusion volume and give the same 4D volume ?
Thanks for any help,
Muriel ROTH

Hi Muriel,
The BrainVISA process explicitely sum all the images of a 4D volume before applying the transformation. This is going to be changed. You can use directly the following command:You can use several interpolations methods or change the geometry of the output image (use --help to see all options).

Hi Yann,
Thank you for your help. I test it today and it works well.
