<div>Hi all,</div>
<div> </div>
<div>Can anybody give me a hint?</div>
<div> </div>
<div>In the DTIstudio software I clicked the "Tensor, Color map, etc" button in the "Calculation" section of the "DtiMap" tab. Then, from the pop-out window called "DTI-Map Options", I saw a choice called "Select a mask-image". Under what situation should we use that choice? Should it be a default choice when the brain has some lesions, given that the lesional area can be at about the same level as the background noise level and thus can be easily wiped out even if we choose a low background noise level from which to create a mask-image?</div>

<div>Thanks a lot,</div>
