Units cortical map

Hello everyone,

I have a small question concerning the compilation of cortical activity sources. When I compile, I end up with cards displaying ''no units''. Does anyone have any idea why this is happening and how to fix it? Thanks in advance for your help!

Kind regards,

Which is the source estimation method that was used?

As some of them are unitless:

I used dSPM

In dSPM (Dale et al. (2000), source estimations based on the default MN method are scaled with respect to the noise covariance. The resulting dSPM maps are a set of z-scores. Units: unitless "z".

Thank you very much for this clear answer :grinning:
