Hi Alfonso and everyone,

We have a Pre-Post design where each subject has 2 sessions. I'm wondering why there is a mean file created for the first session, but not for the second.

During Preprocessing for the second session, I'm getting error messages:  "Mean functional file not found..." and

"/raw_101-2/Resting_State_Analysis_Directory/auswau101-2_restingstate.nii ; run either realignment or ART first, or select the option "first functional
volume as reference" -#coregtomean field- if you prefer to use the first functional volume instead of the mean functional volume as reference)"

Thanks for any help!

Best,

Mary
