Hi,<br><br>In order to get the three BEMs for 3D source reconstruction for<br>subject X, I used: <br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mri_watershed&nbsp;&nbsp; -atlas&nbsp;&nbsp; -useSRAS&nbsp;&nbsp; -surf&nbsp;&nbsp; X/bem/watershed/X<br>&nbsp;&nbsp; &nbsp;X/mri/T1.mgz&nbsp;&nbsp; X/bem/watershed/ws<br><br>which created the BEMs in X/bem/watershed/, but the inner_skull and<br>the brain were significantly distorted, mainly on the left side (the<br>scalp BEM is okay). &nbsp;<br><br>I followed the tutorial on troubleshooting the surfaces in the X/surf/<br>folder, but that does not address fixing these BEMs, so I was<br>wondering if anybody knows how to get around this problem (should I<br>edit the T1.mgz volume and run again?). <br><br>Thank you,<br><br>Silviu Podariu<br>UNMC<br>Omaha, NE<br><br>P.S.&nbsp; Also, I was wondering if there is a utility to reduce the number<br>of vertices of a given surface (i.e. to make a less precise<br>triangulation) at will. I
 thought I may use the pial left and right <br>halves greatly reduced (from about 140k vertices to 10k or less) for<br>the brain surface instead of the mri_watershed output. <br><p>&#32;__________________________________________________<br>Do You Yahoo!?<br>Tired of spam?
