Dear experts,

 

I was trying to define the ILF(inferior longtitudinal fasciculus), IFOF(inferori fronto-occipital fasciculus), arcuate fasciculus, and corpus callosum (CC). But I am not very familiar with the structure of the cortex. So I am considering that if I can segment some roi files from freesurfer aseg+aparc.annot file and changing them into .nii.gz file, Then use these rois as the seed of fiber tracking.   Would you mind teaching  me which rois I choose for each fiber tract if this way is possible?

 

Another question is about the meaing of labels with a wm- begining (e.g. wm-lh-G_frontal_superior) in the look-up table. Does it represent the white matter within the lh-G_ frontal_ superior or represent all white matter that passed through lh-G_frontal_superior?

 

Thanks so much for your concern.

 

 

Yours,

Lulu
