Hi Samuel
<div class=""><br class="">
</div>
<div class="">I hardly ever use FieldTrip on a windows machine, and more in general, handling/maintaining one-shoe-fits-all mex-files on windows platforms is quite challenging. And compilation of mex files an windows platforms can be challenging as well. So
I hope that windows users can chime in a bit here.</div>
<div class=""><br class="">
</div>
<div class="">If you don’t manage to compile the code on your platform, and given that your original problem was with the mex file combineCllusters.mexw64, you could try to delete given mex-file altogether, and fall back to the (slower) m-file.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes and good luck,</div>
<div class="">Jan-Mathijs</div>

<span lang="EN-US" class="">I am having an issue, as seems to be a common occurrence, with mex files and fieldtrip. I have double checked that “mex -setup” is working correctly and have also installed the MATLAB Support for MinGW-w64 C/C++ Compiler (version
22.1.0) already (in Matlab 2022a). I have also installed the most recent version of Fieldtrip on the Website/github. Another important factor: I have ran this exact script before on many computers with no issue. Only on my new laptop (windows 10) am I running
into this issue. I have made sure that all updates are installed.<span class="Apple-converted-space"> </span><o:p class=""></o:p></span></div>
