Hi Folks,<br><br>One of my colleagues had the following issue while using control points. <br><br><br> He re-processed the case after adding some control points (shown in the first figure),<br>but after doing so, the WM was still not included. Is this a typical case, where it would be better to edit wm.mgz instead of adding control points.<br>

<br>Second question: we noticed that some WM was left out from the yellow surface. <br>But when we look at wm.mgz these values of these voxels are in the range 80-95 (shown in the second figure)<br>In such cases should we remove these voxels from wm.mgz (using the right click option) and then include them again ?<br>

That is, this would change the voxel values from 80-95 to 255..<br>I ask this because sometimes, we see that the yellow surface is clipped but there is nothing to include in the wm.mgz since the corresponding values do have some intensity values<br>

<br>Please let me know if you need more information/clarfication about the second question. <br><br>thanks<br>Mehul<br><br><br><br>
