Hi Jessica,

Isaac's observations are spot on.

The "failed command" output is interesting, and makes
me wonder exactly how you are getting that output.
Your script claims to be tcsh, yet it shows the text:

-regress_stim_times imagery_stim_times.*.1D

That should not happen in tcsh. The '*' means the
shell actually sent that character to afni_proc.py,
but since it does not seem to be quoted in your
script, I would guess it is passed by bash.

In any case, as Isaac said, that means there are no
files matching that. You can test this with:

cd /media/LarsonDrive/MRI6/PTSD_Conditioning/Scripts/Linear_Imagery 
ls imagery_stim_times.*.1D

If that shows nothing, then there is a typo in the
name or you are missing a directory prefix.


The "command not found" actually suggests another
odd issue. Perhaps the file is not in Unix format.

What is the output of:

file_tool -test -infile SCRIPT

where SCRIPT is the actual file name?
