Dear AFNI group,

I am wonder how the mentioned program performs the calculation. As long as I know using 3dTproject without -bandpass option will dentrend the signal by a regression using provided vectors and a polynomial order. But, if I use -bandpass option, will the program do the same as above and then filter the frequency? or it applies the filter first and then the regression?

Thanks in advance,
Karel
