Recently our group got a set of Schizophrenia data with .nii extension. This is the first time we deal with this kind of data, so we have some questions:
1. Are these dwi data or dti data?
2. Do we still need to estimate the tensor diffusion?
3. How to read or transform these data to some common softwares, e.g. R, C, Matlab...?
4. Which part(s) of the data is/are useful?
I attached two sample files so that may be helpful.Thanks ahead and we really appreciate your help.
