BaBa21

The BaBa21 dataset provides multimodal neuroimaging data from 21 subjects across 4 sessions, together with a dedicated sub-BaBa21 T1w/T2w template and derived probabilistic tissue atlases (WM, GM, CSF). Three template/atlas variants are included: native sharpened, asymmetric, and fully post-processed (debiased, normalized, CACP re-oriented, cropped, symmetric). A distinctive feature of this resource is the availability of interpolated templates between consecutive sessions (ses-0_to_ses-1, ses-1_to_ses-2, ses-2_to_ses-3), which are automatically generated by the pipeline to facilitate longitudinal and developmental studies.

The T1w and T2w anatomical volumes and manual segmentations (WM,GM,CSF) of a single subject (sub-Prune) are published without embargo. Other twenty subjects can be retrieved on request from the authors and will be published in a next version.

All results are fully reproducible by executing the processing pipeline described at https://github.com/arnaudletroter/BABACOOL.
