Hi
Could someone clarify for me in simple terms what the difference between the
VOI option and plotting option is?
I thought I knew, but after further research on the mailing list I am rather
confused
I wish to plot the time course in selected regions, so perhaps I would be
best choosing the VOI option?
If you choose the plotting option and in particular the contrast estimates
and 90% CI option, what is plotted when you choose 'effects of interest'?
I had 6 contrasts specified in my contrast manager, but spm plotted 9 values
when I chose this option
Lastly, if you chose plotting or VOI, how do you go about extracting the
numerical values so you can do further stats or new graphs in a standard
stats package (including the 90% CI values)?
What is the unit of the value plotted?
Thanks in advance for any assistance you might be able to give me
