Good afternoon, I'm an italian student in Automation Engineering and I'm working with FMRI and Dti files. I'm using spm toolbox for both type of files. For Fmri files I have the spm manual and the pre-processing and processing is very easy, but for Dti files I have some problems: there are not steps for pre-processing (on internet there other softwares for dti files ex. FSL) and I don't find articles about them.Moreover I load in Matlab the Diffusion II utility, but Could I use it for pre-processing? Or Is it used only in the post-processing? and Is there another utility in pre-processing for DTI? Excuse for my english. I do not know if I have been enough. Giuseppe Signorello
