Dear Alfonso, 

I´m a first user of ART and would appreciate if you could give me more information regarding the SPM regressors for outliers and motion. My understanding is that the art_regresion_outliers_and_movement.mat file can be loaded on the Multiple regressors field when specifying the 1st-Level in SPM, could you confirm this please?

Also, I noticed that art creates an additional column at the end of the art_regresion_outliers_and_movement.mat file that does not correspond to either realignment parameters or outliers. Could you please explain what this extra column is representing?

Thank you in advance for your help. 

Best,
Noelia
