Hi Mark, thanks for replying. I went to take a look at the cope 1-4 and
varcope 1-4 files in each gfeat directory...
For the cope files: cope 1 spatial map stays fairly similar across each
gfeat directory, but values are different. Cope 2 spatial maps and values
are different, and as a result cope 3 and 4 are also different.
For the varcope files: spatial maps for all stay fairly similar, but the
values differ.
Since I have done a group comparison separately without the covariates, I am
only interested in contrasts 5-8 from these set of results. Are results from
contrasts 5-8 valid even though variance is changing across contrasts 1-4?
Or, should I change the design so that I only have the last 4 contrasts?
I hope my questions makes sense... Thank you!
