Hi,
I'm trying to perform a seed based resting state analysis, and I was wondering about temporal filtering as part of the preprocessing step. There's an option in Feat to turn on the highpass filter, along with setting the highpass filter cutoff option, but for low pass filtering, I don't see an option to set the value. What frequencies are removed with turning on the low pass filter option in Feat?
The resting state data were acquired with a TR of 2s, and with 195 volumes. Would 100s highpass filter cutoff be appropriate? Any suggestions on the preprocessing steps with seed based resting state analysis?
Thanks,
Amy
