Dear SPMers,
We are analyzing VBM data using spm02.
spm99 analysis allowed the entry of more than 1 nuisance variable if certain
design types were chosen (for ex, Population main effects 2 cond 1 scan/cond
or.. Multi group 2 cond, etc...). In spm02 it appears as if only one
nuisance variable can be put in the design matrix.
We are using Ancova as a design type. Should we use some other design that
will allow us to enter 2 nuisance variables?
thanks very much, teri-)
