Hi,
I’ve been finally able to build rosetta on various machines/compilers. Now I am trying to understand reproducibility/reliability of my builds. I used suggestions from an old post, so I run rosetta -s test.pdb -fixbb -design -natrot on test.pdb from:
rosetta_documentation/docking/tutorial/examples/samplerun/test.pdbAs far as I understood the various options I used, I should got exactly the same results, but I did not. Below is a summary:

sasapack: 2.89 2.89 2.90 2.92 2.91Most of the terms are indentical, whereas some other such as bk_tot, sasa and the total score, are not. Is this discrepancy ok ? I came from the quantum mechanics world, and there numbers between differently built binaries are identical to the 6th digit. Further, I also noticed that some H atoms added during the run to test.pdb have different coordinates in the resulting test_0001.pdb, even by 1 Angs, by using different binaries. Is this ok ? Any explanation ?
Of course, if my binaries have problems, can somebody post the correct numbers ?
Thanks,

Hydrogen placement will depend somewhat on the random number seed – did you try constant_seed in your command line?

Great,
now results match perfectly.
Thanks!
