Thank you Edward, Renaming the relax_fit.so did the job! Nice catch! However, when running the test suite it is falling in the System/Functional tests: Traceback (most recent call last): File "/usr/local/relax-1.3.7/test_suite/system_tests/model_free.py", line 677, in test_opt_constr_bfgs_mt_S2_0_970_te_2048_Rex_0_149 self.value_test(spin, select, s2, te, rex, chi2, iter, f_count, g_count, h_count, warning) File "/usr/local/relax-1.3.7/test_suite/system_tests/model_free.py", line 2051, in value_test self.assert_(spin.f_count in f_count, msg=mesg) AssertionError: Optimisation failure.

Do the source code versions work ok? It could be the a strange combination of python and numpy, together with relax's C modules. You could possibly remove (or rename) the maths_fns/relax_fit.so file and try again. It would be useful to have information about the system to work out what is happening. You can get all the relevant info by typing: $ relax --info This is assuming relax will run at all. Another option would be if you have 'scons', 'numpy', and 'numpy-devel' (or something like that) installed. You could then type: $ scons clean_all to remove the compiled C module, and $ scons to build it again. I hope this helps!

Dear all, Surely this should be a very silly mistake of mine but I can not manage to put to work any of the relax versions above 1.3.6. I just get the message "Segmentation fault" when I type "relax" Do I need to uninstall the previous 1.3.4 version? For now I would like to keep the old one since I have things analyzed on that one. Any help would be much appreciated. Cheers Tiago P __________ Information from ESET NOD32 Antivirus, version of virus
