FC analysis of already preprocessed data
Dear all,
I would like to do functional connectivity analysis using CONN toolbox. I have data that has already been preprocessed and denoised at another research site, also using CONN toolbox. That is, all I have is the preprocessed and denoised functional data (4D) and the preprocessed structural images.
What do I have to do if I want to skip the preprocessing and denoising in CONN toolbox and do only the 1st and 2nd level analyses.
Best,
Maximilian

Hello Maximilian,
Were you able to solve this issue? I'm having the same problema and not finding any answers! How did you work around this?
Thanks in advance,

RE: FC analysis of already preprocessed data
Preprocessing in CONN optional. If your data are already
preprocessed than you're in the clear. As long as you have
information like framewise displacement and head motion parameters,
you can make your own first-level covariates (e.g. scrubbing,
motion). For denoising, you can just move all the nuissance
regressors to the right side, turn off all filtering and other
options, and "run" denoising. However, unlesss you already scrubbed
your data to censor motion, you would need to denoise. Does this
make sense?
