Thank you for your quick reply Jan-Mathijs. </div>

I was expecting something similar, but the opposite is true - higher values for higher resolution (i.e. more sources). Would that indicate I made a mistake in either one of the source models? </div>

Hi everyone,</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<br>
</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I was comparing my source analysis results for a source and leadfield model with resolution 1mm and one with resolution = 1cm and have noticed big differences in source-level power, as estimated with eLORETA. I am using the standard MRI from the Fieldtrip library.</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
In the case of res = 1mm, source power ranges between 1-15, while for res = 1cm, power values are much lower, 0.01-0.5. The sensor-level power (from ft_freqanalysis) ranges between 0.01-3.</div>

</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
When changing the model, I specified cfg.unit = 'cm' for the following functions: ft_prepare_headmodel, ft_prepare_sourcemodel, ft_prepare_leadfield. Is it possible I double-scaled somewhere? </div>

<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Any indication of why this is the case or advice is very much appreciated!</div>
