Qustions about preprocessed rfMRI's output files

[Jinju Liu]

Hi experts,

     I found that the  CIFTI data in the rfMRI's output files called"*_MSMALL_hp0_clean.dtseries.nii". What is the "hp0" mean? Can I use this file to do following analysis? I am very confused with the data's name because they are not called "hp2000".

    Thank you!

For lifespan we moved to linear detrend (hp0) rather than effective linear detrend (hp2000) because the former is MUCH faster.

No that is not a selective denoising technique (that only affects noise and not signal).

Hi experts,

     I have understood that for HCP development,   linear detrend (hp0) replaced effective linear detrend (hp2000). I am wondering  whether  you have performed temporal  filtering for HCPD. If so, which kind of filtering have you performed, lowpass filtering or highpass filtering ?
