预处理数据

T1w相关的数据和fmriprep的差不多,在anat
文件夹下:
- brain mask
- CSF/GM/WM的分割结果
- FAST的Tissue class map
- ANTs的N4 Bias校正后的T1w文件
- MNI和T1w的变形场文件
*_brainmask.nii.gz

Same as above, but in MNI space.

T1 to MNI变形场文件?
DWI的数据在dwi
下,实际可能藏在ses-1
下:
- confunds文件
- brain mask
- b0 template
- fsl的.bval .bvec和MRTrix的.b文件
- 所有b0的重采样DWI
- eddy_cnr
- 根据空间扭曲调整的梯度表
*_confounds.tsv
one column per calculated confound and one row per timepoint/volume*dwiref.nii.gz
The b0 template*desc-brain_mask.nii.gz
The generous brain mask that should be reduced probably*desc-preproc_dwi.nii.gz
Resampled DWI series including all b0 images.*desc-preproc_dwi.bval
,*desc-preproc_dwi.bvec
FSL-style bvals and bvecs files. These will be incorrectly interpreted by MRTrix, but will work with DSI Studio and Dipy. Use the.b
file for MRTrix.desc-preproc_dwi.b
The gradient table to import data into MRTrix. This and the_dwi.nii.gz
can be converted directly to a.mif
file using themrconvert -grad _dwi.b
command.*bvecs.nii.gz
Each voxel contains a gradient table that has been adjusted for local rotations introduced by spatial warping.*eddy_cnr.nii.gz
Each voxel contains a contrast-to-noise model defined as the variance of the signal model divided by the variance of the error of the signal model.
