The AFNI98 directory is old old old. The linux_gcc32 directory (compiled for RedHat 9.0) is up-to-date. Get rid of AFNI98 and use linux_gcc32 in your path.
AFNI98 was a joke name I created about the time Windows 98 came out. As with most jokes, it now seems dated, stale, and pointless.
Here's a joke that is timeless:
A biologist, physicist, and mathematician are standing on the street, observing a house they believe to be empty. Two people enter the house. After some time, three people leave. Each professional interprets this data in the fashion appropriate to his expertise:
Biologist: they must have reproduced.
Physicist: experimental error
Mathematician: if one more person enters the house, then it will be empty again.
