Dear SPMers,
As I understood VOI button with an adjustment option removes the variance explained by the REGRESSORS that are not included in the effects of interest contrast (e.g. moving artifacts). But what is filtered out when one choose an option 'adjust for e.g. main effects' while in SPM design there are no other regressors except the one included in the main effect?
Thanks,
Kind regards
Branislava
