1 GROMACS 2018.4 release notes
2 ----------------------------
4 This version was released on TODO, 2018. These release notes document
5 the changes that have taken place in GROMACS since version 2018.3, to fix known
6 issues. It also incorporates all fixes made in version TODO and
7 earlier, which you can find described in the :ref:`release-notes`.
9 Fixes where mdrun could behave incorrectly
10 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
12 Correct PME forces with free energy without perturbed charges/LJ
13 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
15 With free-energies calculations with lambda not set to zero and no
16 actual perturbed charges or atom types for Lennard-Jones, the Coulomb
17 or LJ PME mesh forces would be scaled with lambda. Note that this bug
18 did not affect the, usual, setup where charges or atom types are actually
23 Add constraint contribution to foreign Hamiltonian differences
24 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
26 The contribution of perturbed constraints was missing from the foreign
27 Hamiltonian values. This is important for free energy calculations,
32 Add mass contribution to foreign Hamiltonian differences
33 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
35 For free energy calculations with perturbed masses, the kinetic energy
36 contribution was missing from the foreign Hamiltonian values.
40 Fixes for ``gmx`` tools
41 ^^^^^^^^^^^^^^^^^^^^^^^
43 Fix mindist output file checks
44 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
46 mindist would not check if the output file needed to print residue names and
47 residue contacts over time was actually defined, leading to errors with
48 empty file name strings.
52 Fix helix segmentation fault
53 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
55 The .tpr file is now read correctly.
60 Fixes to improve portability
61 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
66 Fixed an issue where the log file could sometimes report an incorrect
67 initial dynamic load balancing state
