Hi

I want to use the PESTICA cardio and respiratory output for CONN as covariates within-subjects. For this I have use either 1D MAT or TXT files with the cardiac and respiratory fluctuations at volumec level, and PESTICA I assume outputs at slice level. 

Which files should I use for this and is there any of them in Volumes and not slices? In my case each volume has 36 slices.

Thank you

Kind regards

Eduardo
