Hi,
Getting close.
That looks like an old version of afni, but that should be fine.
(I dropped the @ in later versions because of osx tab completion failures....)
The program will look for a
folder containing the .netcc files.
Try just having the last argument point to the folder instead of the files.
There was a bug some time ago that caused the program to choke if there were non matrix type files in the folder.
It was fixed awhile back so let me know if that happens and I can get you a work around.
Otherwise it is best to update afni.
thanks, Justin
