Dear FSL experts:
Merry Christmas!
I do not know whether the following method of caliculating brain lobe volume is reasonable or not. I hope to get some valuable advice from you.
Modality: MPRAGE
1) Draw a brain anatomical region mask on MNI152_1mm ( or using juelich atlas), I call Brain_template
2) Transform brain_anatomical_mask to native MPRAGE space using invwarp.
3) Segement MPRAGE to GM/WM using FAST, and get pve file( this is the most accurate way to calculate volume according to the UserGuide).
4) Combing GM and WM mask together (brain_lobe_mask) using fslmaths (-add)
5) fslmaths Brain_template -mul brain_lobe_mask to get brain_lobe of different anatomical region.
6) using fslstas to calculate volume of different brain lobe.
I really do not know whether the method is reasonable or not.
Thanks again.
Merry Christmas!!
