[gmx-users] rotacf in Gromacs 5.1 gives unexpected results

[Ramon Crehuet]

Dear all,
I al trying to reproduce the tutorial in:
https://extras.csc.fi/chem/courses/gmx2007/analysis/
When working with Gromacs 5.1, all the correlations (averaged and not averaged) 
give exactly 1.0.
When I run the same conde with Gromacs 4.6 I get the physically meaningful 
results (decaying C(t))
I compiled Gromacs 5.1 with the standard options and `make check` passed all the 
tests.
Is this a known issue? Is it a problem with my compilation? How can I check it?
Thanks in advance,
Ramon
