Surfice is such a fantastic tool, the visualisations are beautiful!

I've been trying to create custom mesh atlases from volumetric atlas files. I know there is a function that converts voxelwise meshes to atlases within the application, though I've been having issues getting this to work ('image does not appear to be an atlas' - tried this with my own atlas as well as several more 'standard' ones I've downloaded, same issue).

My hack-job approach was to export each ROI from the .nii and then convert them to .objs, which was successful but I can only add them in individually as overlays and was hoping to create a single file like the standard atlases included.

Do you have any advice for how to create a single .mz3 atlas file?

I've tried following previous threads and using the 'nii_nii2atlas' matlab tool, but I also encounter issues here (same issue with a couple of atlases):
