<p>Dear Zoltan,<br>

<p>I have indeed recently updated the beamformer tutorial. I just ran it with Matlab 2019a and the most recent Fieldtrip version (available on Github) and the figures look fine to me.<br>
</p>
<p>Could you update your Fieldtrip version and try again?<br>

<div>Hi Jan-Mathijs,</div>
<div><br>
</div>
<div>Thanks for getting back to me. I noticed that the documentation page has changed since my first email, so I created a new script and ran this again. This time no data is loaded from disk during computation, I am using what is produced by the script. The
result is very disappointing, all figures are wrong. I have uploaded the script, the execution log and the output figures. Could you please check what could be wrong here?

<div>Hi Zoltan,
<div><br>
</div>
<div><br>
</div>
<div>Have you checked the values of the numbers in the functional data prior to calling ft_sourceinterpolate? This would give an indication of whether it is an interpolation issue or not.</div>
<div>I suspect that latter, because it seems that the interpolation is pulling ‘activity values’ into areas in the volume for which no functional estimate was provided. </div>
<div>This could happen if the specification of the ‘inside’ field in the source variable, prior to interpolation, behaves unpredictably.</div>
<div>Whether or not this is specific to the Matlab version used, I don’t know. Also, it is unclear what version of fieldtrip you are using.</div>
<div><br>
</div>
<div>What I can see in your script, though, is that the sourcePost_nocon you use to generate the first ‘correct’ 2 figures is loaded from disk, whereas the other source structure (with the ‘incorrect’ interpolation) is not.</div>
<div><br>
</div>
<div>Best wishes,</div>
<div>Jan-Mathijs</div>

<div>I am using the sample data set and the source code from this page but the picture I get for the section "Source Analysis: Contrast activity to another interval" is rather strange. I include here the 3 outputs, first two are correct, third one is the problematic
one. Also included is the source. Matlab version used: R2019a. Could someone check whether it is a script error or perhaps a change in Matlab that generates the odd result?
