Improving the registration quaitliy

Hi, everyone.

I have CEST, DWI, and Perfusion imaging. Since I’m registering DWI, CEST, and PWI imaging into the t1cd imaging, there is a large difference in resolutions between the fixed and moving image. So, I don’t get a good registration quality after using FSL and ITK (antsregsitration). So, any recommendations for other softwares for the better registration quality?

I would recommend Nifty_reg, which I found very robust for multi-modal data or data that are originally very far appart.
