RE: ART clarification
Originally posted by Alfonso Nieto-Castanon:
I've noticed that QC_timeseries (which is the ART_regression_timeseries) is not added to the confound list by default, while the scrubbing covariate (ART_regression_outliers) is, even though both are first level covariates.
What is the difference between the two? Should I add both to the confound list?
I think I should only add the outliers file and the rp*.txt file in the confounds. But I do not understand what the timeseries file is, and why it should be in the effects.
Thank you

"That new .mat file
is simply input into CONN as a first-level covariate which, when
entered as a Confounding effect during denoising, will make
CONN disregard those identified time-points from
any subsequent analysis (by adding a column for each outlier scan
-dummy coding the offending timepoint- to the design matrix used
during denoising to regress out all effects of no
interest)"
Hey Alfonso,I've noticed that QC_timeseries (which is the ART_regression_timeseries) is not added to the confound list by default, while the scrubbing covariate (ART_regression_outliers) is, even though both are first level covariates.
