Dear all,

I would like to ask for your opinion on the use of a band-pass filter with a range of 0.01 to infinity when analyzing resting-state data. I understand that the standard procedure involves using a 0.01 - 0.08 Hz filter in resting-state data to focus on the relevant low-frequency fluctuations while removing confounding artifacts. However, I also came across a video on Conn tutorials' page in which a filter of 0.01 - infinity was employed, and it was suggested that this filter allows for more degrees of freedom, resulting in a slight improvement in denoising quality and connectivity estimation.

Do you believe it is inappropriate to use a band-pass filter of 0.01 to infinity? What might be the implications of such a choice?

Thank you in advance for your insights!

Kind regards,
Carla Soares
