Dear all,<br>
<br>
I am trying to perform PAS tracking on my data. In the mesd step I
get a lot of the following warnings:<br>
<br>
<small>WARNING: Can't use normalization constant 0.0</small><br>
<br>
and sometimes<br>
<small><br>
PM mesd.MESD_Inversion invert<br>
WARNING: optimizers.MarquardtMinimiserException: Infinite
objective function in mrqcof.</small><br>
<br>
I read that this might happen if background voxels are included in
the calculation. Is this a critical issue or can I proceed anyways?<br>
<br>
Best<br>
Peter<br>
