AFNI program: 3dresample
Output of -help
/var/www/html/pub/dist/bin/linux_gcc32/3dresample - reorient and/or resample a dataset
This program can be used to change the orientation of a
dataset (via the -orient option), or the dx,dy,dz
grid spacing (via the -dxyz option), or change them
both to match that of a master dataset (via the -master
option).
** Warning: this program is not meant to transform datasets
between view types (such as '+orig' and '+tlrc').
For that purpose, please see '3dfractionize -help'.
------------------------------------------------------------
usage: /var/www/html/pub/dist/bin/linux_gcc32/3dresample [options] -prefix OUT_DSET -inset IN_DSET
examples:
/var/www/html/pub/dist/bin/linux_gcc32/3dresample -orient asl -rmode NN -prefix asl.dset -inset in+orig
/var/www/html/pub/dist/bin/linux_gcc32/3dresample -dxyz 1.0 1.0 0.9 -prefix 119.dset -inset in+tlrc
/var/www/html/pub/dist/bin/linux_gcc32/3dresample -master master+orig -prefix new.dset -inset old+orig
note:
Information about a dataset's voxel size and orientation
can be found in the output of program 3dinfo
------------------------------------------------------------
options:
-help : show this help information
-hist : output the history of program changes
-debug LEVEL : print debug info along the way
e.g. -debug 1
default level is 0, max is 2
-version : show version information
-dxyz DX DY DZ : resample to new dx, dy and dz
e.g. -dxyz 1.0 1.0 0.9
default is to leave unchanged
Each of DX,DY,DZ must be a positive real number,
and will be used for a voxel delta in the new
dataset (according to any new orientation).
-orient OR_CODE : reorient to new axis order.
e.g. -orient asl
default is to leave unchanged
The orientation code is a 3 character string,
where the characters come from the respective
sets {A,P}, {I,S}, {L,R}.
For example OR_CODE = LPI is the standard
'neuroscience' orientation, where the x-axis is
Left-to-Right, the y-axis is Posterior-to-Anterior,
and the z-axis is Inferior-to-Superior.
-rmode RESAM : use this resampling method
e.g. -rmode Linear
default is NN (nearest neighbor)
The resampling method string RESAM should come
from the set {'NN', 'Li', 'Cu', 'Bk'}. These
are for 'Nearest Neighbor', 'Linear', 'Cubic'
and 'Blocky' interpolation, respectively.
See 'Anat resam mode' under the 'Define Markers'
window in afni.
-master MAST_DSET: align dataset grid to that of MAST_DSET
e.g. -master master.dset+orig
Get dxyz and orient from a master dataset. The
resulting grid will match that of the master. This
option cannot be used with -dxyz or -orient.
-prefix OUT_DSET : required prefix for output dataset
e.g. -prefix reori.asl.pickle
-inset IN_DSET : required input dataset to reorient
e.g. -inset old.dset+orig
