Dear All,
Will you please tell me the newest version of GROMACS that can be installed under Cygwin?

4.5.5, per http://www.gromacs.org/Downloads/Installation_Instructions/Cygwin_HOWTO

Your problems during make after correct configuration are probably related to http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-fork-failures, and will be transient, as I have suggested to you before.

I have tried, the elder version (3.3.1 version)can be installed under cygvin sucessfully under cygvin, but the 4.5.5 and 4.5.4 version could not.
I am looking forward to getting a reply from you on it.
Cheers,
Wholly

Hi Wholly,
It would be better to install a more recent version of gromacs. The tutorial should state which version it is written for.
Cheers,

Dear All,
I am running the on-line tutorial http://www.bevanlab.biochem.vt.edu/Pages/Personal/justin/gmx-tutorials/lysozyme/06_equil.html. By "grompp -f nvt.mdp -c em.gro -p topol.top -o nvt.tpr", with the nvt.mdp downloaded as attached following, I got the following error message:

You can safely ignore this if your system doesn't have any
LINCS-constrained bonds;
for water molecules we normally use the analytical SETTLE algorithm
instead.

I am looking forward to getting a message on what is the problem.
