I generated a label file using the command 

mri_vol2label --c $SUBJECTS_DIR/bert/mri/brainstemSsLabels.v10.mgz --id 173 --l midbrain.label 

the content of the label file is probably in RAS format. My question is how to locate a point in freeview using the given coordinates of the label file? 

i.e the label file content is as follows

-1  4.000  -20.750  33.750 0.0000000000
-1  3.500  -20.750  33.750 0.0000000000

I am unable to locate 4.0, -20.750, 33.750 in the volume shown through freeview. 

I also want to find out the overlapping planes of two label files, for which I need to convert the label file into voxal coordinates (or may be there is any other simpler way, i dont know) 

Any help shall be highly appreciated.
