Hello,

I'm trying to install FreeSurfer (freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0.tar.gz) on an Ubuntu-10.04 x86_64 AMI hosted on Amazon's EC2, but after following the installation instructions I am unable to complete the "Testing your Freesurfer Installation" section. I am not trying to use any of the visualization tools, just "recon-all -s bert -autorecon1" and the mri_tools, like mri_convert.

I get the following error when I run "recon-all -s bert -autorecon1" (recon-all.log attached)
...
Found 3 runs
/usr/local/freesurfer/subjects/bert/mri/orig/001.mgz
/usr/local/freesurfer/subjects/bert/mri/orig/002.mgz
/usr/local/freesurfer/subjects/bert/mri/orig/003.mgz
Checking for (invalid) multi-frame inputs...
ERROR: input(s) cannot have multiple frames!
/usr/local/freesurfer/subjects/bert/mri/orig/001.mgz has  frames
...

I saw a previous post with the multi-frame error (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg18444.html) and tried running "mri_info" to include in this email, but mri_info does not execute. Actually none of the mri_* tools are working and do not provide usage information when executed without any parameters.

Any idea what I what I did wrong, or could this have to do with running freesurfer on EC2?

Thanks for your help!
