Can't project source PSD to cortex

[julama]

Hi,

I have calculated sources from EEG epochs (sLORETA) and from the sources PSD (welch). When I try to project the PSD to the cortex I get the error "no cortex available for the default anatomy". Because I have used a head model to compute the sources it is unclear why it's not working for PSD (see screenshot). What am I missing?

Thanks and best regards

The PSD was computed using Scouts (as indicated in the file name), thus there is not a value for each vertex to be plotted on the cortex.
Try computing the PSD with the option Use scouts unselected.

That's it! Thank you
