I was unable to extract parts of the cortex with the commands you had told me to try last time. I realised then that it was because recon hadn&#39;t finished running and I was using partially processed data. So I tried running it again. Here below is what I got. Since I&#39;m using a partitioned machine space may be a problem but it doesn&#39;t seem to say so. <br>

Thanks in advance for the advice.<br><br clear="all"><span style="color: rgb(51, 51, 255);">#--------------------------------------------</span><br style="color: rgb(51, 51, 255);"><span style="color: rgb(51, 51, 255);">#@# Cortical ribbon mask Sat Mar 20 07:17:29 GMT 2010</span><br style="color: rgb(51, 51, 255);">
