Ah, you are probably having the opposite problem.
By default now, afni runs in the background (it
spawns a new process). That means your 3dcalc
command is running (and presumably failing) long
before you even get your hands on the mouse.

Hitting ctrl-c probably does nothing. Maybe you
could even hit Enter to get a new prompt.

Add the -no_detach option to make afni stay in the
foreground, so that 3dcalc does not run until afni
is done.


Note that your described example could be done
directly with 3dclust, no need to run afni. But I
guess that was just a random example.
