We used a set of randomly selected dHCP 2nd data release data to recompute this (N = 50) (Not overlapping with the datasets from DHCP 1st that were used to create the template)
The robust template space was computed using an affine transformation model using robust registration (mri_robust_template) using the full DHCP 1st release (N=40).
For the infants the new scaling factor is: 358628
Recomputed with MCRIB2 (N=10): 346193
1. compute transform to template
2. take determinant
3. atlas_icv = theScaleFactor / atlas_det
atlas_det = MatrixDeterminant(atlas_lta->xforms.m_L) atlas_icv = (theScaleFactor * (10 * 10 * 10)) / atlas_det
