Hi,

Unless you want to construct contrasts that use the derivatives you don't need to use Real Evs and Original EVs will get the job done.

Hi,

I'd like to confirm that - when setting up a basic FEAT analysis (in Full model setup) using the standard HRF convolution and adding the temporal derivative - one should setup the contrasts for the Original not the Real EVs.

Thanks,
