<div dir="ltr" class="">Dear all,

</div>
<div class="">I came across an issue about alignment while analyzing source-level connectivity by following the tutorial (<i class=""><a href="https://urldefense.com/v3/__https://www.fieldtriptoolbox.org/tutorial/networkanalysis_eeg/*computation-of-the-forward-model__;Iw!!HJOPV4FYYWzcc1jazlU!uvz1WO7GtQJtPHUj7C5BgCs1xW_f2CKjLmjoohcZB8kNPf39E_meFRgaigxb4t1nKC9r5uKwkHCPwGA$" class="">https://www.fieldtriptoolbox.org/tutorial/networkanalysis_eeg/#computation-of-the-forward-model</a></i>).
I could not align the standard_1005.elc with the headmodel_eeg downloaded in <span style="color:rgb(33,37,41);font-family:-apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,"Helvetica Neue",Arial,sans-serif,"Apple Color Emoji","Segoe UI Emoji","Segoe UI Symbol";font-size:16px;text-align:justify" class=""> </span><a href="https://urldefense.com/v3/__ftp://ftp.fieldtriptoolbox.org/pub/fieldtrip/tutorial/networkanalysis_eeg/__;!!HJOPV4FYYWzcc1jazlU!uvz1WO7GtQJtPHUj7C5BgCs1xW_f2CKjLmjoohcZB8kNPf39E_meFRgaigxb4t1nKC9r5uKwMPJLx7k$" class="">ftp://ftp.fieldtriptoolbox.org/pub/fieldtrip/tutorial/networkanalysis_eeg/</a>.</div>
<div class=""><br class="">
</div>
<div class="">However, the standard_1005.elc could be well aligned with the standard_bem headmodel with the type of "dipoli" (<a href="https://urldefense.com/v3/__https://www.fieldtriptoolbox.org/template/headmodel/__;!!HJOPV4FYYWzcc1jazlU!uvz1WO7GtQJtPHUj7C5BgCs1xW_f2CKjLmjoohcZB8kNPf39E_meFRgaigxb4t1nKC9r5uKwFhqy_Fs$" class="">https://www.fieldtriptoolbox.org/template/headmodel/</a>).
Then the problem must come from the difference between two headmodels. However, there was little information about the headmodel_eeg with the type of "openmeeg". </div>
<div class=""><br class="">
</div>
<div class="">So what is the difference between those two headmodels provided by different tutorials? How could I align the standard_1005.elc well with the headmodel_eeg with the type of "openmeeg"?</div>
<div class=""><br class="">
</div>
<div class="">Thank you in advance.</div>
