Dear users,

I am really new to mristudio (spm user so far) and can't register to the forum. 
I would be really thankful if anyone could help me out.

My question is brief:

I want to coregister the tracts I got from there:
http://lbam.med.jhmi.edu/cmrm/Data_Yajing/fiberMenu.htm

= Probabilistic Fibers Atlas

with a standard template, e.g. the ICBM 2009c nonlin
(http://www.bic.mni.mcgill.ca/~vfonov/icbm/2009/mni_icbm152_nlin_sym_09c_nifti.zip)

I thought that the fibres should already be in that space as they are in the "eve" space and "eve" is in tge ICBM-152 space according to the Neuroimage Paper ("We used a single-subject white matter atlas in the ICBM-152 space, called the “Type II Eve Atlas”").
But when I display e.g. the corticospinal tract above the ICBM 2009 image it looks displaced:

Trying to coregister the two images with spm does not seem to work. Is there anything I can do?

Thank you so much for your help.


A second small question is what format the files on 
http://lbam.med.jhmi.edu/cmrm/human_whiteMatter/template_whiteMatter.php
are in. They seem to be nifti as the extension is .img but there are no .hdr files available...

Thank you!

Yours, sincerely, Andreas Horn
