inorm-sess error - Freesurfer

23 Jun 2008


      Hi,
I'm trying to get around the problems from my previous post: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07669.html
I am now trying to use mri_convert to convert from nifti to bshort using the following command: mri_convert -i rfkoch-0021-00144-000144-00.nii -it nii -o fspm2_000.bshort -ot bshort
The bshort files seem to be created but then when I run inorm-sess I get the following error. The odd thing is that when I used mri_concat on exactly the same .nii files (as mentioned in my previous post) I was able to run inorm-sess with no errors... What is the difference between these two commands?
The inorm error:
Warning: Matrix is singular to working precision.

??? Error using ==> betainc at 35
X must be in the interval [0,1].
The exact output from the command is pasted below.
Here is 
the output of bugr:
