AFNI program: 3dWarp

Usage: 3dWarp [options] dataset
Warp (spatially transform) a 3D dataset.
--------------------------
Transform Defining Options: [exactly one of these must be used]
--------------------------
  -matvec_in2out mmm = Read a 3x4 affine transform matrix+vector
                        from file 'mmm':
                         x_out = Matrix x_in + Vector

  -matvec_out2in mmm = Read a 3x4 affine transform matrix+vector
                         from file 'mmm':
                         x_in = Matrix x_out + Vector

     ** N.B.: The coordinate vectors described above are
               defined in DICOM ('RAI') coordinate order.
               (Also see the '-fsl_matvec option, below.)
     ** N.B.: Using the special name 'IDENTITY' for 'mmm'
               means to use the identity matrix.
     ** N.B.: You can put the matrix on the command line
               directly by using an argument of the form
       'MATRIX(a11,a12,a13,a14,a21,a22,a23,a24,a31,a32,a33,a34)'
               in place of 'mmm', where the aij values are the
               matrix entries (aij = i-th row, j-th column),
               separated by commas.
             * You will need the 'forward single quotes' around
               the argument.

  -tta2mni = Transform a dataset in Talairach-Tournoux Atlas
              coordinates to MNI-152 coordinates.
  -mni2tta = Transform a dataset in MNI-152 coordinates to
              Talairach-Tournoux Atlas coordinates.

-----------------------
Other Transform Options:
-----------------------
  -linear     }
  -cubic      } = Chooses spatial interpolation method.
  -NN         } =   [default = linear]
  -quintic    }

  -fsl_matvec   = Indicates that the matrix file 'mmm' uses FSL
                    ordered coordinates ('LPI').  For use with
                    matrix files from FSL and SPM.

  -newgrid ddd  = Tells program to compute new dataset on a
                    new 3D grid, with spacing of 'ddd' mmm.
                  * If this option is given, then the new
                    3D region of space covered by the grid
                    is computed by warping the 8 corners of
                    the input dataset, then laying down a
                    regular grid with spacing 'ddd'.
                  * If this option is NOT given, then the
                    new dataset is computed on the old
                    dataset's grid.

  -gridset ggg  = Tells program to compute new dataset on the
                    same grid as dataset 'ggg'.

  -zpad N       = Tells program to pad input dataset with 'N'
                    planes of zeros on all sides before doing
                    transformation.
---------------------
Miscellaneous Options:
---------------------
  -prefix ppp   = Sets the prefix of the output dataset.
