[Camino-users] mesd warnings

[Peter Neher]

Dear all,

I am trying to perform PAS tracking on my data. In the mesd step I get a 
lot of the following warnings:

WARNING: Can't use normalization constant 0.0

and sometimes

PM mesd.MESD_Inversion invert
WARNING: optimizers.MarquardtMinimiserException: Infinite objective 
function in mrqcof.

I read that this might happen if background voxels are included in the 
calculation. Is this a critical issue or can I proceed anyways?

Best
Peter
