Meanuas file missing
Dear experts, 

I am new to Conn processing, and ran into an error while preprocessing longitudinal fMRI data. I could not find the answer anywhere on the forum. I have 2 fMRI sessions and 2 anatomical scans for each participant. 

After running the "functional realignment & unwarp (subject motion estimation and correction)" preprocessing step, Conn created the meanuas file just for the session 1 scans, however not for the session 2 scans. Therefore, when I am trying to run the "functional coregistration to structural" step, which is next in my preprocessing pipeline, I get the following error message (copied below). It is looking for the meanuas file, however it wasn't created during the previous step. I also kept "first functional volume as reference' as unchecked. Would you happen to know what I should do? 

Thank you
Anna
