Hi,

The tool that the GUI calls is "cutoffcalc".

All the best,

Mark

Hi group,

I guess another way of asking the same question is, in FEAT / Misc, you can click the button, 'Estimate High Pass Filter'.

I am wondering what program/script is used after that button is clicked?

Best,

Daniel

Dear FSL group,

When I am performing a first-level stats + post-stats analysis and load a functional data, the FEAT automatically determines the high pass filter cutoff from the default 100s to 60s for me.

I am wondering, 

(1) through what mechanism/algorithm, does FEAT determine the high pass filter cutoff value?

(2) because I am doing my analyses using script and oftentimes this high pass filter cutoff value is pre-determined, how can I calculate the most appropriate high pass filter cutoff value for each individual functional data like what FEAT does?

Best,

Daniel
