XFM2DEF(1)
NAME
xfm2def - convert a MNI transform file to a deformation volume
SYNOPSIS
xfm2def [options] input.xfm def_vol.mnc
DESCRIPTION
- xfm2def takes an input transform input.xfm that can consist of a series
of concatenated transforms in a single xfm file and converts this into
a single deformation volume that is output as def_vol.mnc. Note that
the output is not a tranform file itself, you can then make use of this
volume in a MINC tranform by creating an .xfm file as such:
- MNI Transform File
- Transform_Type = Grid_Transform;
Displacement_Volume = def_vol.mnc; - The output resolution and sampling of the deformation grid must be specified or a default size will be used. (100x100x100 1mm steps centred around the origin).
