Dear All,
I want to use cingulate bundle as ROIs more exactly mask for fiber tracking.
Can someone explain please how I can use the JHU-WhiteMatter-labels-1mm.nii.gz
and their labels JHU-WhiteMatter-labels-1mm.txt to get a mask of my cingulate
bundle in my diffusion space for each individual subjects?
Do I need to draw ROIs and how I can do this more accurate?
Is the following correct:
1) mri_convert -rl [path to subject]/DATA/s001/nodif.nii.gz -rt nearest
JHU-WhiteMatter-labels-1mm.nii.gz s001_aseg2dif.nii.gz
2) fslmaths /[path to subject]/DATA/s001_aseg2dif.nii.gz -uthr 35 -thr 35
/[path to working directory]/ROIS/Cingulum_(cingulate_gyrus)_R.nii.gz
3) fslmaths Cingulum_(cingulate_gyrus)_R.nii.gz –div 35
Cingulum_(cingulate_gyrus)_R.nii.gz
If I want to run for the cingulate bundle the tractography should I repeat this
steps for:
36 Cingulum_(cingulate_gyrus)_L
37 Cingulum_(hippocampus)_R
38 Cingulum_(hippocampus)_L
Thank you for your help.
Antonella
