NIST MNI minipipeline
The documentation was provided by Vladimir S. FONOV, research associate at NIST.
The modalities of out/sub-<id>/ses-2/tal/tal_sub-<id>_ses-2_<modality>.mnc
are:
- T1w
- flair
- brain
These files contain anatomical MRI scans of UK Biobank after processing with in-house tools, based onminc-toolkit-v2
version 1.9.17
-
nonuniformity correction using
N4
-
linear intensity normalization using histogram to match
MNI-ICBM152 2009c
intensity ranges -
linear stereotaxic registration to MNI-ICBM152 2009c space using
bestlinreg
tool version from 20180117 -
linear warping into
MNI-ICBM152 2009c
space -
brain-masking using
BEaST
-
second nonuniformity correction using
N4
with BEaST brain mask -
second linear intensity normalization
They were linearly (rigid body) co-registered with T1w scans and warped using the concatenated transform of FLAIR and T1w
There are also .xfm
files:
out/sub-<id>/ses-2/tal/tal_xfm_sub-<id>_ses-2.xfm
- describes linear (9 parameter) transformation from native to MNI-ICBM152 2009c space for T1w scans
out/sub-<id>/ses-2/tal/tal_sub-<id>_ses-2_brain.mnc
- was produced using an in-house brain segmentation tool (deep learning based) from out/sub-<id>/ses-2/tal/tal_sub-<id>_ses-2_t1w.mnc
