Hello all.
I am wondering what the best approach would be to pre-whiten resting
state functional data.
My first though was to create a design matrix which is just a constant
"on." I see that this is then "corrected" to be a column of zeros.
Then I ran
film_gls and passed it my data and this design matrix and gave the flag
-output_pwdata.
This ran fine and created a prewhitened time series.
So my question is: Is that it?
Would this be the correct way to do it?
Thank you,
Jason.
