Dear Rui,

unfortunately the current version of the Toolbox does not support F-tests.
Dual-Regression runs the following randomise command:

• randomise -i [input] -o [output] -m [mask] -d [design] -t [t-contrast] -n 500 -x -T -V

If you want to perform F-tests, you will have to edit some commands manually. Open dR/scripts+logs/drD. At the end of each line, you will find the randomise command. Append -f [design.fts] and then rerun it.
You will also have to edit drE to merge the output.


We are currently working to include these features in the next release. It will be possible to change the number of permutations and the -f and -e tags will be supported.


Best regards,

Jorge Manuel
