Dear Sebastian,
Split your matrix into two separate lines and define both age and IQ as a separate nuisance variable. I haven't done this for a while but it used to work through the GUI.
Good luck,
Alexander

Subject: [SPM] Nuisance variable naming in AnCova
Hello SPMers,
I am doing some analysis with AnCova in SPM 2.
We have two nuisance variables: Age and IQ. I entered those in a separate text-file (simple matrix, 2 lines) and loaded it in the dialog "nuisance variable" via "spm_load".
In the next dialog SPM asks for the "Nuisance variable name". However I can only enter one name, but I want to enter both, age and IQ, in order to distinguish them later on in my design matrix.
Is there any trick on how this could be done ?
Thanks in advance !
Regards,
Sebastian
