I am trying to run a simple fullfactorial (mixed ANOVA) 2nd-level design
in SPM5. (this is because I could not do this in SPM2 in a straighforward
manner).
Factor1= group, levels =2, independent, unequal variance
Factor2= task, levels=2, dependent, equal variance.
Group1 has 8 patients, Group2 has 16 controls.
Should be easy right? But nooo...
I get an error during estimation (appended below). If I change Factor1's
variance to "equal" it works, in that the contrasts are set up and I can
see the results. (Works regardless of Factor2 having equal or
unequal variance.) But this makes no sense because presumably
the patients and controls have unequal variance. I am using the latest
version 714 updates. Don't have any earlier updates version to try ...
64-bit linux machine, recompiled the mex files.
Any help is most appreciated.
