RE: Problem displaying surface-level analyses
Hi Amy,
One issue there is that Freesurfer aparc*+aseg.mgz files are not really surface-space files like the associated lh.aparc*.annot files (i.e. defined in fsaverage space), they are instead projected back to subject-space (i.e. in the same space as your structural data), so if you want to import those in CONN as ROIs you need to associated them with your "subject-space" functional data, rather than your "surface-space" data (i.e. select the option that reads "compute average timeseries from secondary dataset #5 (subject-space data)"
Hope this helps
Alfonso

Hi Alfonso,
The ROIs are surface-based subject-specific ROIs from Freesurfer's DKTatlas+aseg.mgz files. They are associated with the apart.DKTatlas+aseg text file for the labelling.
The following advanced options are selected: atlas file, subject-specific ROI; mask with grey matter.
They are associated with the functional data "compute average timeseries from secondary dataset #1 unsmoothed volumes".
I conducted preprocessing with CONN's default surface-based pipeline.
Thanks,
Amy
