Hi,
I'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.
Could there be a bug in the program?
