Hi, Amy-
Glad the shell changing was pretty straightforwad (sigh, Macs always try to complicate life...).
Ummm, that's good about installing the AFNI binaries *except* you shouldn't need (nor want) to use "sudo" there. The "sudo" power, enabling your command to have admin privileges, is only necessary if you install things into the system-side of things; by default, we install the AFNI binaries into a directory called "abin" that sits in your home directory-- you don't need admin privileges to write there. The benefit of this is that it keeps things simple to update, and you don't need to be an admin to update your local binaries.
Soooo, actually I would recommend removing the "abin" directory in your home directory, and re-running the @update* command without the "sudo".
Once you do that, can you please copy+paste the following:
A)
which afni
B)
which suma
C)
afni_system_check.py -check_all
and paste the outputs here?
thanks,
pt
