This was a bug in the minfx library (https://gna.org/projects/minfx/) that relax uses.

My system is Ubuntu-9.04:
When I perform a gridsearch, exclusively for m5, with the lower and upper bounds set to: lower=[0.111, 0, -0.0], upper=[0.111, 1.00, 200] I keep seeing the following message during the calculations:

"Min f: 3474.82

k: 3860 xk: [ 0.111, 0.066667, -0] fk: nan

Increment: array([ 5, 16, 16])

Params: array([ 0.111, 1. , Inf])

Min params: array([ 0.111 , 0.06666667, -0. ])

f: nan

Min f: 3474.82

k: 3861 xk: [ 0.111, 0.066667, -0] fk: nan

Increment: array([ 6, 16, 16])

Params: array([ 0.111, 1. , Inf])

Min params: array([ 0.111 , 0.06666667, -0. ])

f: nan

"

And at the end the tauS is zero for all spins and the S2s is always close to 1.

Attached follows the script that I am using and a truncated sample of my data set (I hope it is not too truncated!) as well as the results that I am getting.

If you need more info let me know.
Thanks
Regards
Tiago P
