I am trying to run 3dANOVA with 4 levels. The program runs great with ~945 participants, however, I would like to run the program on 2,000 participants. When I try running 3dANOVA on all of my participants, I receive the error: ** FATAL ERROR: Program 3dANOVA: too many data files. I did try using the -@ option (getting rid of all ), which works to fix this issue for 3dttest++, but this did not seem to work here.
I am using a iMAC OS X El Capitan Version 10.11.6. AFNI binaries were updated 12/8/16.
