Actually, the date just before that part is what I was looking for. For example, on my computer, this is the output:
$ afni -ver
Precompiled binary linux_ubuntu_12_64: Apr 28 2015 (Version AFNI_2011_12_21_1014)
(To be honest, I have no idea how to interpret that Version string-- I think it's some legacy thing.)
And what is the output of the following steps? Take the output of the first command command, and then replace the 'afni' part with the following in the second command:
$ which afni
SOMETHING/afni
$ ls SOMETHING/1d*
Please paste the full output (I'm looking to see if 1dDW_Grad_o_Mat is listed among all the other binaries where 'afni' is).
Thanks,
pt
