每次处理图像之前，定义路径

export TUTORIAL_DATA=/Users/yourname/tutorial_data/
cd $TUTORIAL_DATA
export SUBJECTS_DIR=$TUTORIAL_DATA/buckner_data/tutorial_subjs
cd $SUBJECTS_DIR

load several output volumes, such as brainmask.mgz and wm.mgz; the surfaces, rh.white and lh.white; and the subcortical segmentation, aseg.mgz.

freeview -v \
good_output/mri/T1.mgz \
good_output/mri/wm.mgz \
good_output/mri/brainmask.mgz \
good_output/mri/aseg.mgz:colormap=lut:opacity=0.2 \
-f good_output/surf/lh.white:edgecolor=blue \
good_output/surf/lh.pial:edgecolor=red \
good_output/surf/rh.white:edgecolor=blue \
good_output/surf/rh.pial:edgecolor=red

Some notes on the above command line:

good_output is the name of the subject
The flag -v is used to open some of the most commonly used volumes including:
- brainmask.mgz : skull-stripped volume primarily used for troubleshooting
- wm.mgz : white matter mask also used for troubleshooting
- aseg.mgz : subcortical segmentation loaded with its corresponding color table and at a low opacity. For more information on the subcortical segmentation, see here.
The flag -f is used to load surfaces
- white & pial surfaces are loaded for each hemisphere & with color indicated by 'edgecolor'
