brede_vol_origin - Return origin of volume in 'vol' structure
origin = brede_vol_origin(V)
Input: V 'Vol' structure
Output: origin 3-element vector with origin in voxel-indices
indexed from one
Get the 'origin' field from the 'vol' structure. If the origin
field is not defined the origin will be determined from the
'x', 'y' and 'z' fields. If these are neither defined the the
origin is reported as the middle of the volume, e.g., if
the volume is 91 voxel wide then the origin for the x
coordinate will be returned as 46.
Example:
f = fullfile(fileparts(which('brede')),'xml','cerebellum1.xml');
V = brede_read_xml2vol(f);
