Dear MRI Study,
in SPM12, you can edit config/spm_cfg_factorial_design.m at line 579 so
that it reads:
fnums.num = [Inf 1];
You will then be able to enter factor numbers [2 3 4].
That said, a better option would be to follow a similar approach than
the one described by Will in this email:
https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=spm;2b10ca53.1510
and use several second level models (two-sample t-tests here).
Best regards,
Guillaume.
