<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am reading the FieldTrip documentation on creating an FEM model and see that the following tissue types are output from the segmentation process:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Gray<o:p></o:p></p>
<p class="MsoNormal">White<o:p></o:p></p>
<p class="MsoNormal">Csf<o:p></o:p></p>
<p class="MsoNormal">Skull<o:p></o:p></p>
<p class="MsoNormal">Scalp<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Q1: Since I am using a 256 channel EGI system with electrodes over the lower part of the head and face, I absolutely need to be able to include air voxels as well. Anyone have any knowledge of such a possibility?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Q2: Beyond that I would also like to include other tissue types such as fat, muscle, and eyeball (vitrious). I suppose I could find other segmentation software to simply create a more varied segmentation and insert it in the processing
pipeline, but would like to know if that would mess anything up.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Q3: Next, can the FEM handle anisotropic conductivities for white matter and skull?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Q4: has anyone out there actually used the FDM model? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
