Hi freesurfers,<br><br>1. I am a new user of freesurfer. I want to measure,compare cortical thickness in corresponding regions of the cortex in a group of subjects. Is there a description of steps involved in doing this?<br>
<br>From what I have read till now, I know that I can create ROIs and use the instructions on <a href="http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness">http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness</a> to get the thickness values and then repeat the same for different regions/subjects. I would like to know if there is a workflow available for doing the same.<br>
<br>2. I am facing the tksurfer &#39;sliver&#39; problem on a virtual CentOS machine run on Windows XP using VMWare Player for using Freesurfer. Has anyone experienced a similar problem and is there any way to correct it?<br>
<br>Any inputs on these two issues will be very helpful.<br><br>Thanks!<br><br>Regards,<br>Jaichander<br>
