Introduction to neuroimaging analytical variability.

In this introduction, we will review the evidence of analytical variability in the three main neuroimaging modalities, structural MRI, functional MRI (task, resting state and dynamic functional connectivity), and diffusion MRI. We will review the impact of the analytical flexibility on scientific conclusions and show that in many instances, conclusions will differ as a function of a chosen analytical pipeline. We will consider the rationales for choosing one pipeline over others, and lay out the motivation for this course.
