Hello,

1) You had previously referenced a paper to me on DTI [Citation: Rajagopalan V, Jiang Z, Stojanovic-Radic J, Yue GH, Pioro EP, et al. (2017) EA Basic Introduction to Diffusion Tensor Imaging Mathematics and Image Processing Steps. Brain Disord Ther 6: 229. doi: 10.4172/2168-975X.1000229] and it really helped me understand the basics of the math behind it.

However, I did have a pressing question: Is DTI an imaging technique or a modeling technique?

2) I was reading about how images get reoriented during conversion from acquisition form (dicoms) to perhaps a software-viewer form (like nifti) [https://people.cas.sc.edu/rorden/mricron/dcm2nii.html]. Does this mean the images one is analysing using these softwares is inferior to raw data and in doing so (converting them from dicom to nifti format), it poses the risk of flipping images and hence hampering the study?

3) If you have more such helpful resources that could enable me to understand the basics of this stuff, I'd hugely appreciate it. 
I apologise for my lengthy questions in advance, I am just starting out in this field and think that I could learn a lot from whatever interactions I have with experts like you.

Thank you.
