xfm2def(1)

Usage

xfm2def [options] input.xfm def_vol.mnc

Overview

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 transform file itself, you can then make use of this volume in a MINC transform 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).
