[MINC-users] nonlinear transformation

[Oliver Winz]

Hello everybody,

i have a problem concering nonlinear transformation to stereotaxic 
space. The final MRI after transformation is very suspect. Maybe i 
forgot a very important part in the processing steps and someone can 
give a hint.
Here is my complete procedure:


 > dcm2mnc input*.IMA destdir/
 > mritotal inputMRI.mnc outputTrans-Lin.xfm
 > mritotal -nonlinear -transformation outputTrans-Lin.xfm inputMRI.mnc 
outputTrans-NonLin.xfm
 > mincresample -transformation outputTrans-NonLin.xfm -like 
average305.mnc inputMRI.mnc outputMRI-toTAL.mnc

 > mritotal -version
Program mritotal, built from:
Package MNI AutoReg, version 0.98r, compiled by owinz at medpc66 
(i686-pc-linux-gnu) on 2005-02-24 at 17:58:14

I'm working on Pentium V 3.0 GHz, running SuSE Linux 9.2 with kernel  
2.6.8-24.18-smp
I get the DICOM MRI's from a Magneton VISION 1.5 T, Siemens, Erlangen, 
Germany) using a 3D T1-weighted MPRAGE sequenze (voxel size = 1 x 1 x 1 mm³)

Everyone who's interested in a screenshot, please let me know, i will 
send to you.
Thanks in advance!!
Greetings,
Oliver
