RE: Importing new QC metrics as 2nd-level covariates after rerunning preprocessing?
Dear Jeff,

In the Setup.Covariates (1st-level) tab, selecting the menu 'covariate tools. Compute new/derived first-level covariates' and then selecting the option 'Compute scrubbing (thresholded list-of-outliers covariate)' allows you to re-create the 1st-level scrubbing covariate applying the same or different thresholds from the ones chosen during preprocessing, and this option will also automatically re-compute the 'QC_ValidScans', 'QC_InvalidScans', 'QC_MaxMotion', 'QC_MeanMotion', 'QC_MaxGSchange', and 'QC_MeanGSchange' 2nd-level covariates with the new list of outliers (see "help conn_convertl12l1covariate" for details). 

Hope this helps
Alfonso

We ran our preprocessing using the default intermediate QC/ART settings, which resulted in QC second-level covariates from the 5z/0.7mm ART thresholds.  Needing to be a bit more conservative with ART thresholding, we reran the preprocessing routine using the conservative ART settings, which did update the masks and regressor files.  However, how do we generate a new set of QC metrics in the second-level covariate section to reflect the more conservative ART settings (i.e., QC_valid_scans for new ART threshold results)?  Rerunning the preprocessing pipeline does not automatically generate a new set of QC second-level variables.

Thanks,
Jeff
