[Camino-users] Bad data?

Dear all,

   I performed the following sample simulation with random seeds by 
spawning jobs in our cluster.

datasynth -walkers 100000 -tmax 1000 -voxels 1 -seed  75191 -p 0.0 
-schemefile myScheme_mod.scheme -initial uniform -substrate cylinder 
-packing hex -cylinderrad 1E-6 -cylindersep 2.1E-6 > 
regcylinders_v1_seed75191_1E6.bfloat

Remaining jobs are different in the seed option which are generated 
using numpy's Random state method. I have attached herewith the 
submitted jobs  and the results obtained.
commands.txt --> job list
myScheme_mod.scheme --> scheme file
regcylinders_v1_seed20750_1E6.bfloat  --> Synthetic DW data
regcylinders_v1_seed20750_1E6.txt  -- > 96 entries for each direction in 
the scheme file.
DiffTensorv1_seed20750.Bdouble    --> Diffusion Tensor
DiffTensorv1_seed20750.txt  -->

Exit code   6.000000E00 Bad data?
                 1.151293E01
                 4.361172E-11
                 4.156295E-12
                 -3.311438E-12
                 3.916382E-11
                 8.841888E-12
                 1.693537E-09

Is it due to the wrong parameter I have used for simulation? may be the 
seed?
Any help will be appreciated.

Thanks and regards,
Lekshmi
