HFor the SPGR dataset
example (ÔnakedÕ image files):
to3d -xFOV 120A-P -yFOV 120S-I -zSLAB 70.0L-77.6R \ -prefix anatNaked -2swap -spgr N.*å-xFOV 120A-P says that the x axis of
the images runs from 120 mm Anterior to 120 mm Posterior
å-yFOV 120S-I says that the y axis of
the images runs from 120 mm Superior to 120 mm Inferior
å-zSLAB 70.0L-77.6R says that the z
axis of the slices runs from 70 mm Left to 77.6 mm Right
íFOV refers to the coordinates of the
outer edge of the first voxel to the outer edge of the last voxel along the relevant axis (x
and y, in most cases)
íSLAB refers to coordinates of the
center of the outermost voxels (z=slice direction, in most cases)
å-prefix anatNaked gives the prefix
for output dataset filenames (in this case, anatNaked+orig.HEAD
and anatNaked+orig.BRIK)
å-2swap means to byte-swap the images
while reading them
å-spgr means to label this data as
being of SPGR (SPoiled GRass) type
åN.* means to read the images from the
files whose names start with string ÒN.Ó and end with anything (Ò*Ó is a wildcard)
