RE: Using entire freesurfer regions in seed-to-voxel FC analysis

Hi Alfonso,


 


Thanks for your message!


 


In terms of specifics...


1) How do I increase the number of aCompCor components? What number would you recommend increasing to?


2) Would you recommend increasing ALL motion parameters (i.e., timeseries, realignment and scrubbing) to 1st or 2nd order derivatives? What about the white matter and CSF?


3) For using a more conservative definition of outliers, this can be done during the ART pre-processing step, correct? Would I choose "Use conservative settings (95th percentiles...)" rather than the intermediate or liberal options? Can I perform this step without having to run the SETUP process all over again?


4) Would adjusting the band-pass filter be a good idea? Right now, I just used the default of 0.008 to 0.09.


 


Sorry for all these specific questions - I've just never run into these denoising issues before! My QC plots have always looked great in the past.


 


Thank you!


Kaitlin
