Hi
What do you get if you type
echo X`cat ../../subjects_for_ica.txt`X
Have you tried this without the quotes around the first argument (WHATEVER...), which you shouldn't generally use.
Finally - in the output log directory, look at all files and see if any have error messages in them?
Cheers.

Now I'm proceeding to the dual regression, something which is quite new for me, and I have a problem.
