Hi,
I'm not sure about the validity of the file - you might want to remove
the /Skip line?
But I'm thinking that you should probably not be using a design.grp
file as it is unlikely with an ANOVA design that your groups are
separable into fully separate sub-models - try just leaving the
design.grp option out of randomise? Note that randomise doesn't model
variance groups separately like FLAME (in FEAT) does, anyway.
Cheers, Steve.
