Hi, <br><br>I&#39;ve been trying to use mri_segstats on a FA map with a 
white matter parcellation file (wmparc.mgz) but there might be a problem
 in the program. When I open the fa.stats output file, all the values 
(std.dev, etc) are 0.0000  for the 2009 table parcellation ids. However,
 when I use the label id 251 (corpus collosum) from the first few labels
 on the list, I get a value. When I use the corpus collosum id for more 
current labels like the aparc 2005 and 2009,  I get 0.0000 again. <br>

<br>Could there be a bug in the program? <br><br clear="all"><br>-- <br>Elizabeth C. Gutierrez<br>
