What is EEG data converted into using sLORETA

1

Hello Francois,

Sorry for this question, i must have missed this in the tutorials. I'm using minimum norm imaging, sLORETA. What is my EEG data converted into using this method? For example, when using EGIs head model software, they use sLORETA and the current units are expressed in nano-amps. I'm assuming the units for sLORETA are universal no matter what platform we use (EGI or brainstorm).

For example, if i was making a graph using source data, the y axis would be something like "Amplitude (nA)" ?

Thanks very much for your time.

sLORETA is a unitless measure.
Units for the different methods are described in the introduction tutorials:
