Hi Troels,
Running this system test on a 64-bit Linux system (Mageia 4), I see the

I guess this is what you see too. On a 32-bit Linux VM (Mageia 4) I see:

The reason for this is due to truncation artifacts. The chi-squared
value might be decreased if the data in
test_suite/shared_data/dispersion/bug_22146_unpacking_r2a_r2b_cluster/ns_cpmg_2site_star_full/
is generated on a 64-bit computer and it is output to 15 or more
decimal places. But the chi-squared value is pretty close to zero, so
you could just decrease the accuracy of the chi2 check to make the
test pass. It is clear that despite a chi2 value of 2e-5 here, the
code is working correctly and the test should pass.

Edward

At home, I have python 32 bit.
At work, it is 64 bit.
Can that have something to do with it?

Hi Edward.
I am experiencing something weird.
At my mac, this passes:
Relax_disp.test_bug_22146_unpacking_r2a_r2b_cluster_NS_STAR
but not at my linux box.
How is it for you?
