Hello,

Specifically related to your jar test failures:

None of those errors are located within the actual results of the
calculation, just the functional form of the restraint potential.  It's
possible the test was changed, but the saved files were not updated.  It's
also possible that defaults were changed, but again not updated.  In any
case, R1 only signifies the point at which the potential becomes linear
(rather than quadratic), so the two biassing potentials (the one used to
generate the test and what's actually being run when you make test) differ
only past 0 degrees for the torsion.  The fact that none of the results
differ probably means it's safe to use this functionality, you just have to
be careful that the restraint function used by the program is what you
expect it to be (i.e. check that
I remember a while ago having this exact test failure, but I don't have a
copy of amber10 lying around anywhere to refer back to.
As to the tip5p error, the intel don't print out those last two lines, and
I'm not sure why, but they are documented.  I don't think there's anything
actually wrong with that test.
The only two tests that look worrisome are the LES 2temp.out (for some
reason Etot is never getting computed for that frame), and the NEB test
where a bunch of extra stuff is being dumped into the output file.  Those
two tests you'll want to be careful with.  The only one I haven't mentioned
(rdc) is just benign round-off, as has been mentioned in a previous post in
this thread.
All the best,
Jason
