hi,<br><br>I noticed an interesting thing today. I used read_annotation function in matlab to load an .annot file, i.e., [Vertexes,Label,Colortable]=read_annotation(AnnotFile);<br><br>But some labels in Labels were 0&#39;s. They did not appear in the 5th column of Colortable.table. And 0 was the only label that i couldn&#39;t find in the 5th column of Colortable.table. All other labels were fine. <br>

<br>Any idea what the cause of 0&#39;s as labels might be? <br><br clear="all">Cheers, Forrest<br>
