Hi Edward,
Yes I am sorry about the private label. I set it initially to private
because I was going to include the structure of the protein attached, but
then I realized that I didn't need to send the whole thing. Eventually I
forgot to set the label back to public. So, yes, you can use the info as you
wish to try and solve the issue - including the test suite.

Hope to hear from you soon.
Cheers
TP

Hi,

Is there any reason this bug report has been made private?  The data
is so truncated, there's nothing much anyone can do with it.  The
privacy tag is usually reserved for security issues whereby it needs
to be kept private until a fix is found and released.  Then the bug
can be made public.  I'm looking into this now, but I'm not exactly
sure what is happening.  Is it ok if I include this data, or part of
it, into the relax test suite?  This will significantly help in the
debugging and will make sure this bug never returns!

Cheers,

Edward

Details:

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
