I have results that were obtained only on the surface - meaning I have a surface .mgh file to upload but no .nii.gz file to accompany it. The upload to NeuroVault seems to require a volumetric image. I guess I can project my results to MNI152 and upload the resulting file, but it seems a bit strange that people will then look at the volume files where there will be many 0s or NaNs anywhere that is not defined as cortex.
I would prefer people to only see the surface files. Is that possible?
