Hello, Freesurfer experts:

I am new to freesurfer and try to install the newest version of freesurfer in Ubuntu system. I closely followed the instructions, and the only difference is that I installed it in my Documents, instead of local folder.

Below is the output after ¡°source $FREESURFER_HOME/SetUpFreeSurfer.sh¡±

-------- freesurfer-Linux-centos4-stable-pub-v5.0.0 --------

Setting up environment for FreeSurfer/FS-FAST (and FSL)

FREESURFER_HOME /home/jie/Documents/freesurfer/

FSFAST_HOME /home/jie/Documents/freesurfer//fsfast

FSF_OUTPUT_FORMAT nii

SUBJECTS_DIR /home/jie/Documents/freesurfer//subjects

MNI_DIR /home/jie/Documents/freesurfer//mni

Everything seems fine and I also added the .license file to the freesurfer folder.

But when I test it by ¡°tkmedit bert orig.mgz¡±, it reponds ¡°Illegal instruction¡±

If I type in ¡°recon-all¡±, it will show

¡° Required Arguments:

-subjid <subjid>

-<process directive>¡­... ¡± and the other arguments.

How to fix the problem and make Fressurfer run? Any help is appreciated. Thanks a lot!

Jie
