<div>Greetings!</div>
<div><br>
</div>
<div>Thank you for sharing the camino tools! I have tried to follow the tutorial for tracking and use the test data provided. I have used itksnap to generate a rather rough ROI and then called track, when I get warnings like these:</div>
<div><br>
</div>
<div>
<div>1. </div>
</div>
<div>
<div>Processing seed 502 of 1275optimizers.MarquardtMinimiserException: Infinite objective function in mrqcof.</div>
<div>optimizers.MarquardtMinimiserException: Infinite objective function in mrqcof.</div>
<div>optimizers.MarquardtMinimiserException: Infinite objective function in mrqcof.</div>
<div><br>
</div>
</div>
<div><br>
</div>
<div>And</div>
<div>2. </div>
<div><br>
</div>
<div>optimizers.MarquardtMinimiserException: Singular Matrix in gaussj - 2 </div>
<div><br>
</div>
<div><br>
</div>
<div>I would very much appreciate your help in understanding this messages, and if there is something I can do about it! </div>
<div>I have the feeling it might have to do with ROI definition…</div>
<div><br>
</div>
<div>With best wishes & Many thanks!</div>
