Description

We developed a population-specific brain atlas target adolescent collision-sport (American football, soccer) athletes, based on the MRI scans from the longitudinal database of Purdue Neurotrauma Group. The brain atlas was developed in an effort to facilitate multimodal neuroimaging studies, specifically to minimize bias introduced in spatial normalization, improve sensitivity of voxel-wise statistical analysis, and therefore better clarify the mechanisms that lead to traumatic brain injury in adolescent athletes, which is one of our long-term commitments to this vulnerable population. Image processing software including FSL, ANTs, and Freesurfer were used to create the templates (T1-weighted and DTI) and semantic labels (cortical and white matter parcellations). To scale and speed up the atlas creation, we established a high-throughput high-performance computing workflow which integrated Open Science Grid and Purdue Community Clusters.
