Scheduled service maintenance on November 22

On Friday, November 22, 2024, between 06:00 CET and 18:00 CET, GIN services will undergo planned maintenance. Extended service interruptions should be expected. We will try to keep downtimes to a minimum, but recommend that users avoid critical tasks, large data uploads, or DOI requests during this time.

We apologize for any inconvenience.

4D multi-channel neonatal brain altas

This repository contains a 4D parametrized atlas multi-channel atlas of the normal term neonatal brain development during 37-44 weeks PMA presented in (Uus et al., 2021). The atlas was constructed from 170 normal term MRI datasets from the dHCP project.

The atlas includes:

  • 4D fitted structural MRI channels (common 0.75mm and unbiased 0.6mm space): T1w, T2w, T1w/T2w
  • 4D fitted diffusion MRI channels (common 0.75mm and unbiased 0.6mm space): DTI(FA, MD, RD), ODF(ODF, TDI), NODDI(FICVF, FISO, ODI), average DWI, DKI(MK), microFA
  • parcellation maps (M-CRIB-WM-based WM ROIs, high rate change "gamma" ROIs and the original dHCP tissue ROIs)
  • Gompertz model gamma maps (outputs of 4D fitting corresponding to the signal change rate in time)
  • transformations from 37 to 44 weeks PMA timepoints (affine in MIRTK format and nonlinear warps in MRtrix3 format)
