Hi Rick,
I thought it might be a corrupt file issue as well, so I downloaded the most recent version for OSX, again, and pointed my environment to it. That did not resolve the issue.
I have been trying to reply to Bob's last post for some time, and include BRIK files. Those attempts result in the pages getting timed out. Here's hoping that this comes through better:
node02:~/sullivan/1032/briks sgifford$ echo $0
-bash
node02:~/sullivan/1032/briks sgifford$ which afni
/Network/Servers/fileserver.hebb.private/Volumes/BSP_new/cluster/local/afni/afni
node02:~/sullivan/1032/briks sgifford$ which 3dTstat
/Network/Servers/fileserver.hebb.private/Volumes/BSP_new/cluster/local/afni/3dTstat
node02:~/sullivan/1032/briks sgifford$ afni -ver
Version AFNI_2007_05_29_1644
