Hi, I'm a new FS user just trying to run through the tutorials. In the Group Analysis tutorial, doing the multiple comparisons correction, when I run mri_flmfit-sim I get a malloc() memory corruption error. The output is below. I am running the VirtualBox Xubuntu 12.04 Freesurfer 5.3.0 version on a PC with 64-bit Windows 7 and 3472 MB of RAM (assigning more RAM than that causes the VirtualBox to crash). I setup a shared folder on my E: drive to store the buckner tutorial data. Had to add fsuser to vboxsf using usermod to be able to access the data from xubuntu. Also can't setup symbolic links on a shared folder so I had to copy the fsaverage dataset to the E: drive. Not sure if that is a good way to set things up but I couldn't find much guidance on the best way to do this. Found lots of mailing list threads related to this error, but none of them actually seem to provide a solution. Any help would be appreciated.
