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
