You don't say what type of computer system you are using. If you have upgraded a Linux distribution from libc2.1 to libc2.2 (do "ls -l /lib/libc*" to figure it out), and you are running binaries compiled against libc2.1, then you need to upgrade. The AFNI site provides binaries for both libc's, or you can compile your own AFNI.
