Hi Christine,

usually this means it is running out of memory. I think we recommend more than 2G for a virtual machine, can you increase the amount of RAM?

Greetings from St. Louis. I recently installed Freesurfer version 4.5 on my Windows XP OS PC after attending your training course held at our institution, Washington University. The install went fine, and I was able to make it through all the checks in your setup and installation series on your wiki page. I attempted to then run a data set of my own and ran into the following error during autorecon2 which I have included the lines of output right before it as well:

I am running with 4G of RAM and a quad-core processor. At first I thought it was because of the 2GB max space limit in VMware so I even built and mounted a 100GB drive internal to VMware and ran all the data from there. Additionally when I check the disk space after this error it shows it only used ~1% of the 100GB mounted disk in VMware so I know I have room. Output from typing 'bugr' per your request on wiki is the following:

FREESURFER_HOME: /usr/local/freesurfer

Build stamp: freesurfer-Linux-centos4-stable-pub-v4.5.0

Debian version: 5.0

Kernel info: Linux 2.6.28-11-generic i686

Any thoughts or guidance as to what may be going wrong? I fully admit to my novice status with Freesufer and kindly look forward to any and all advice. I found one reference to a similar problem searching through your Freesurfer support Old Archive but the response from your organization was just a further inquiry for additional information so I was unsure as to how to proceed. Thank you in advance for the help!
