Hi All,

Wasn't support for CHARMM27 supposed to be included in this release? I thought there had been a few discussions about it over gmx-developers regarding the CVS code, which I haven't checked out in a while. I also see, for example, #ifdef _FF_CHARMM in spc.itp, tip3p.itp, etc, but there are no force field files for CHARMM, or reference to it in FF.dat. Am I missing something, or was CHARMM not included in the release?

Thanks.

Hi everybody,

We've just released a maintenance version 4.0.3 with a bunch of bugfixes and minor enhancements - all issues in bugzilla that had been settled to be bugs have been fixed.

You can find it in the usual place:

ftp://ftp.gromacs.org/pub/gromacs/gromacs-4.0.3.tar.gz

Some of the fixes are:

* Improved domain decomposition grid and separate PME node setup: it will succeed more often and the error messages are clearer. * mdrun will now tell which atoms are out of range when the domain decomposition fails due to too long bonded interaction distances.
* Fixed crashes and hangs which could occur with mdrun -nosum.
* Fixed checkpoint reading which would fail with SD/BD and separate PME nodes. * Fixed normalization of the averages and fluctuations at the end the log file by nsteps+1 (was nsteps). * With mdrun -rerun the averages in the log file and printed by g_energy are now correct. * The mdrun performance print is now correct when the run is terminated before the last step. * In the pull code the sign of the virial contribution is fixed (it was incorrect in 4.0 and 4.0.2, it was 0 in version 3.3).
* Made the pull code work again with particle decomposition.
* Several fixes for configuration and compiling on IBM machines, especially for the Blue Gene.
* Added some more input checks in grompp and mdrun.
* Fixed gmxlib/mdlib library dependencies for linking with other code.
* Fixed Coulomb forces in nb_generic.c for user modified code.
* Several non-critical fixes in other GROMACS programs.
* Compiler warnings for gcc 4.3 have been addressed
* Compatible with libtool 2.x and automake 1.10.1 (only matters for developers)


Cheers,

Erik
