Dear list,
I intend to extract time series from my VOI's for later DCMs (obtained from a t-test, i.e emotional greater than neutral material). In several papers, they often use an appropriate F-contrast and adjust it for eigenvariate extraction (by the effect of interest) - how can I adjust the emotional vs neutral t contrast (if needed)?
In general, should one use t or F contrasts for time series extraction and is adjusting always recommended?
Many thanks for your help
