In addition to Tzvetan’s comment: please do not try and interpolate directly onto the inflated cortical sheet. You also need to provide the non-inflated sheet for the interpolation (after which the interpolated data can be displayed on the inflated sheet).

Hi Vehab,
You have to normalize the individual volume to the MNI template. So use ft_volumenormalise first and try again. Or, if you used MNI aligned grid that specify the source.pos = template grid.pos.
Good luck

Hi all,

I am having an issue in projecting my results on a (template) cortical map in FT and using ft_sourceplot. It seems a subset of the brain activations has only been projected (see attached).

Any comment would be appreciated!

Best,
Vahab
