Hello. I have a question about fMRIPrep.
I ran fMRIPrep with the -- dummy -scans N
and I understand that the N scans are not really discarded and just treated as dummy scans. However, I did not include the dummy scans into onset timing so I would like to discard N dummy scans before runnning the first level GLM with SPM12.
Now, I’m planning to discard the N scans of preprocessed functional data and the corresponding rows of confound timeseries before the first level analysis. Is this correct way?
Thanks, in advance.
