Hi Meishan,

I imagine the issue may be that the new ROI file is set to extract data from the unsmoothed volumes (so CONN is looking for the wau* files, i.e. prior to smoothing)? If so, simply go to the Setup.ROIs tab click on your new atlas ROI, and change the option that reads "extract from unsmoothed volumes" to "extract from functional data"

Hope this helps

Alfonso

Thank you! This file actually does not exist in the first place - we started with the swau* files which were preprocessed already in SPM from the data source. Is there a way I can ask CONN to not to look for this file?

Additionally, this error has not appeared untill we imported a Schaefer atlas as ROIs (we have imported other atlas and performed 2nd level analysis multiple times). The error itself seemed to be irrelevant to Schaefer atlas, but it did appear after we imported this atlas. Everything has been performed on a computing cluster, would this have something to do with it?

Thank you so much!
