<p class=MsoNormal><span lang=EN-US>It depends on how you use this tool. For
example, after you start tensor calculation, you get an initial "DTI Map
Option" window, in which you can find two checkboxes at the lower left
corner saying "create ,,,,,". If you proceed to "standard linear
fitting", then you should get one row of theory image and another row of
error (subtracted) images.<o:p></o:p></span></p>

</div>
<div>
<p class=MsoNormal><span lang=EN-US>In this window, if you choose to use
"pixel rejection", instead of "standard linear fitting",
you get 3 options in "Verify the results" section. Here we recommend
to use "binary mask" instead of "error map". If you choose
"binary mask", the bottom row is not error maps, but showing which
pixels were rejected due to large errors. <o:p></o:p></span></p>

suspect your images did not contain obvious outliers and therefore the bottom
