[Freesurfer] Snowy background for T1 images

Hello,

I keep seeing a snowy background for my T1 structural images.

Here is my info:

FREESURFER_HOME: /usr/local/freesurfer/stable4

Build stamp: freesurfer-Linux-centos4-stable-v4.5.0-20100311

RedHat release: CentOS release 5.3 (Final)

Kernel info: Linux 2.6.18-128.7.1.el5 i686

NMR Center info (/space/freesurfer exists):

machine: seymour

SUBJECTS_DIR: /space/seymour/1/users/folate_subjects/

PWD: /space/seymour/1/users/folate_subjects

ssh seymour setenv SUBJECTS_DIR /space/seymour/1/users/folate_subjects/ cd /space/seymour/1/users/folate_subjects

The command I entered and one of the subjects we are seeing this with -

tkmedit-sess -s FB0011089A -a fmcsm5_functionals -c Cond1vFix

Is this a problem? What can I do to fix this?
