AFNI program: 3dZcat

Usage: 3dZcat [options] dataset dataset ...
Concatenates datasets in the slice (z) direction.  Each input
dataset must have the same number of voxels in each slice, and
must have the same number of sub-bricks.

Options:
  -prefix pname = Use 'pname' for the output dataset prefix name.
                    [default='zcat']
  -datum type   = Coerce the output data to be stored as the given
                    type, which may be byte, short, or float.
  -fscale     = Force scaling of the output to the maximum integer
                  range.  This only has effect if the output datum
                  is byte or short (either forced or defaulted).
                  This option is sometimes necessary to eliminate
                  unpleasant truncation artifacts.
  -nscale     = Don't do any scaling on output to byte or short datasets.
                   This may be especially useful when operating on mask
                   datasets whose output values are only 0's and 1's.
  -verb         = Print out some verbositiness as the program
                    proceeds.

Command line arguments after the above are taken as input datasets.
A dataset is specified using one of these forms:
   'prefix+view', 'prefix+view.HEAD', or 'prefix+view.BRIK'.

INPUT DATASET NAMES
-------------------
This program accepts datasets that are modified on input according to the
following schemes:
  'r1+orig[3..5]'                                    {sub-brick selector}
  'r1+orig<100.200>'                                 {sub-range selector}
  'r1+orig[3..5]<100..200>'                          {both selectors}
  '3dcalc( -a r1+orig -b r2+orig -expr 0.5*(a+b) )'  {calculation}
For the gruesome details, see the output of 'afni -help'.

Notes:
* You can use the '3dinfo' program to see how many slices a
    dataset comprises.
* There must be at least two datasets input (otherwise, the
    program doesn't make much sense, does it?).
* Each input dataset must have the same number of voxels in each
    slice, and must have the same number of sub-bricks.
* This program does not deal with complex-valued datasets.
* See the output of '3dZcutup -help' for a C shell script that
    can be used to take a dataset apart into single slice datasets,
    analyze them separately, and then assemble the results into
    new 3D datasets.
