[Neuroimaging] non linear deformation

[valabregue]

Dear all

Can anyone point me out some python library to apply non linear 
deformation to the image ?

This is for data augmentation so I do not need to do a non linear 
registration, but just a way to apply a random smooth deformation field.

Is there in nibabel support for reading deformation field (from spm or 
ants) and then to apply it ?


Many thanks

Romain
