<p class="MsoNormal"><span style="font-family:Helvetica"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Helvetica">Has anyone tried developing an FEM volume conduction model for stroke survivors (<a href="http://www.fieldtriptoolbox.org/tutorial/headmodel_eeg_fem)">http://www.fieldtriptoolbox.org/tutorial/headmodel_eeg_fem)</a>.
I was wondering, how have you modeled the lesioned volume? Have you modeled it as CSF, and if so, how did you do that?

<p class="MsoNormal"><span style="font-family:Helvetica"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Helvetica">I used the code shown below and it appears to me that the lesions are not getting modeled as CSF; they appear to be modeled as scalp and skull.

<p class="MsoNormal"><span style="font-family:Helvetica">cfg.output = {'gray','white','csf','skull','scalp'};<o:p></o:p></span></p>
