Hi - ok - that's good - so FAST with the basic options works. Now could you do the same with the more comlete test which is run inside FEEDS, ie type fast -od /tmp/structural_brain -ob -or -e -ov structural_brain presumably this will fail - the errors messages will hopefully give us some clue why. One possibility is that you are running out of swap space - you may want to watch top whilst it is running to check that this is not the problem. Thanks, Steve. Stephen M.
