AFNI program: 3dNwarpApply
Output of -help
Usage: 3dNwarpApply [options] sourcedataset
Program to apply a nonlinear 3D warp saved from 3dAllineate -nwarp_save
(or from 3dNwarpCalc) to a 3D dataset, to produce a warped version of
the source dataset.
OPTIONS:
--------
-nwarp www = 'www' is the name of the 3D warp dataset
-wfac fff = Scale the warp by factor 'fff' [default=1.0]
-source sss = 'sss' is the name of the source dataset
++ That is, the dataset to be warped
-master mmm = 'mmm is the name of the master dataset
++ Defines the output grid.
++ If '-master' is not used, then output
grid is the same as the source dataset grid.
-newgrid dd = 'dd' is the new grid spacing (in mm)
++ This lets you resize the grid without
needing to use '-master'.
-interp iii = 'iii' is the interpolation mode
++ Default interpolation mode is 'wsinc5' (slowest, bestest)
++ Available modes are the same as in 3dAllineate:
NN linear cubic quintic wsinc5
++ The same interpolation mode is used for the warp
itself (if needed) and then for the data being warped.
-prefix ppp = 'ppp' is the name of the new output dataset
-quiet = Don't be verbose :-(
-verb = Be extra verbose :-)
NOTES:
------
* At present, this program doesn't work with 2D warps, only with 3D.
* At present, the output is always in float format, no matter what
absurd data type is in the input.
* Program 3dNwarpCalc could be used to operate on 3D warps:
++ e.g.: catenate (compose) them; invert or square root them.
++ 3dNwarpCalc also has built-in a slightly simplified version
of 3dNwarpApply's functionality, so that you can calculate a
warp and apply it to a dataset in one program.

=========================================================================
* This binary version of 3dNwarpApply is NOT compiled using OpenMP, a
semi-automatic parallelizer software toolkit, which splits the work
across multiple CPUs/cores on the same shared memory computer.
* However, the source code is modified for OpenMP, and can be compiled
with an OpenMP-capable compiler, such as gcc 4.2+, Intel's icc, and
Sun Studio.
* If you wish to compile this program with OpenMP, see the man page for
your C compiler, and (if needed) consult the AFNI message board, and
http://afni.nimh.nih.gov/pub/dist/doc/misc/OpenMP.html
