[gmx-developers] reading non-gromacs trajectory formats and adding of default extension

[chris.neale at utoronto.ca]

Hi Roland,

You mention that now "The default extension is only added if the  
specified file does not exist." Does this mean that I can now do this:

mdrun -deffnm this -o /dev/null -c /dev/null -g /dev/null

This would be very convenient to alleviate demand on our file system  
where we are running very many very short simulations and the  
opening/closing is beginning to cause problems.

Thanks,
Chris.
