From: Challenges and best practices when using ComBAT to harmonize diffusion MRI data
Illustration of the seven steps of a typical Pairwise-ComBAT harmonization of two sites underlying the effect of each variable of Eq. (15). From the raw data in a) to the harmonized data in j). The gray curves in b) illustrate the overall trend of the population from site 1 and site 2, whereas the scatter plots show the values of the \(J_i\) subjects of each of each site i. Details on how the metric/age population shaded plots are computed are provided at the end of Experiments section.
