Each sample from BraTS Challenge data consists of four MR images (native T1, post-Gd-contrast T1-weighted, T2 FLAIR, T2-weighted) and one image containing three reference segments as label numbers. These series were imported into a database and the five series per subject were associated. The reference segment series was labeled as SEGMENT in the Association interface.
As the data was already cropped and coregistered, no additional preprocessing was applied.
