Hi Rick,
I am sorry it has taken a while to get back to you. What would happen in the GUI is that the "please wait for dataset computations and disk I/O" message would come on. If I watched in the shell, it would list each of the 8 files as it wrote them. When it got to 8/8 the messages in the shell would stop and the "please wait" screen in the GUI would not go away. None of the other buttons in the GUI would work except "done." It did this for every subject whose functional data I talairached. But now if I delete those files and do it again, I can't replicate the problem! It works just as it always did. The "please wait" screen goes away, and I can do other things in AFNI. I am sorry for taking your time on this, but I swear I was not hallucinating!
Linda
