Hello Erin,
Do you have the high-pass filter checked on in the Pre-stats section of the GUI? If so then this will be applied to the confounds in the text file.
Kind Regards
Matthew

> I noticed that when I input a text file containing columns of 0s and 1s into the confound EV option in FEAT (i.e., motion outliers), some of the columns are being modified. Please see the attached design matrix. You can see the first 3 conf regressors appear to have been modified (the baselines are curved).
