Z scoring the source data

Hello,

We conducted source analysis using the sLORETA method up to standardization. Is it necessary to z score the output (i.e., normed data) when we are doing a group analysis?

Thanks,
Claire

Hi Claire,

The Z-score normalization is not required when conducting source analysis using sLORETA as it already normalizes the data. You can find more information on our Source Estimation tutorial page.
