Hi,

Can you please send us the exact commands you tried to run
and the exact error messages they gave.

Also, have you checked that all the original analyses were correct?

If it creates a log directory, please also look at the contents of
files there too and let us know of any errors.

All the best,
	Mark

The manual says that I should use the glm in the FSL program with 1 EV and the matrix should be 0 for one group and 1 for the other. I tried to create the matrix by changing the number of inputs but then I canīt save it.
