Hello!
This is a statistical question rather than afni specific but since I'm using 3dTproject I was wondering what the relationship between polort and high-pass filter is. If I use a polort of 2 it will remove very low frequencies which is what high-pass filtering does, is that correct?
Also why does the 3dTproject help file say "It makes no sense to use a value of pp greater than 2, if you are bandpassing out the lower frequencies!". This is probably related to my question above but I don't understand why "it makes no sense".
Is there also an option to perform only high-pass filtering with 3dTproject?
Thanks!
