Hi,
I am using the high pass filter in Feat on my BOLD data (6s ON / 14 s OFF) and I was wondering what kind of filter is implemented? On the feat-log page I can't find the commandline which is used (is it flsmaths using the -pbtf option?) . Also it recommends a filter cutoff off A+r length in seconds, this seems quite strict as it can affect the activation evolution. But then it also depends on what kind of filter is implemented, i.e. what is the filter roll-off. Is there a way to look up what filter is used and how it affects the temporal frequencies using a certain cut-off setting in Feat?
thanks!
