AFNI program: abut
Output of -help
ABUT: put noncontiguous FMRI slices together [for to3d]
method: put zero valued slices in the gaps, then
replicate images to simulate thinner slices
abut [-dzin thickness] [-dzout thickness] [-root name]
[-linear | -blocky] [-verbose] [-skip n+gap] ... images ...
-dzin the thickness value in mm; if not given,
taken to be 1.0 (in which case, the output
thickness and gap sizes are simply relative
to the slice thickness, rather than absolute)
-dzout the output slice thickness, usually smaller than
the input thickness; if not given, the program
will compute a value (the smaller the ratio
dzout/dzin is, the more slices will be output)
-root 'name' is the root (or prefix) for the output
slice filename; for example, '-root fred.'
will result in files fred.0001, fred.0002, ...
-linear if present, this flag indicates that subdivided slices
will be linearly interpolated rather than simply
replicated -- this will make the results smoother
in the through-slice direction (if dzout < dzin)
-blocky similar to -linear, but uses AFNI's 'blocky' interpolation
when possible to put out intermediate slices.
Both interpolation options only apply when dzout < dzin
and when an output slice has a non-gappy neighbor.
-skip 'n+gap' indicates that a gap is to be inserted
between input slices #n and #n+1, where n=1,2,...;
for example, -skip 6+5.5 means put a gap of 5.5 mm
between slices 6 and 7.
More than one -skip option is allowed. They must all occur
before the list of input image filenames.
