Hi,<div><br></div><div>In reconstructing some normal adult MPRAGEs, I&#39;ve had a couple of different fairly large errors that I haven&#39;t been able to fix:</div><div>(1) In a handful of subjects, more than half of the brain is lost, I think during the skullstripping step (ie, isn&#39;t present on the white matter or brainmask volumes later). This seems to be primarily on scans from a 3T Siemens with a 32channel head coil. I have tried adding control points, but this doesn&#39;t help. </div>

<div>(2) In another handful of subjects, a large portion of the cerebellum is designated as cortex, and is labeled on the aseg maps. </div><div><br></div><div>Any suggestions on how to fix these two types of problems? </div>

<div><br></div><div>thanks,</div><div>Nicole</div><div><br clear="all"><div><br></div>-- <br>Nicole Senecal<br>Neuroscience Graduate Group<br>Kable Lab<br>3720 Walnut St., Room C37<br>Philadelphia, PA  19104<br>Lab phone:  215-746-4371<br>
