[gmx-users] Gromacs 5, TNG, and older trajectory formats

[Magnus Lundborg]

Hi,

The new TNG format and library do not affect other formats. So, if you 
do not write/read TNG everything should work as before. There are some 
TNG features that are not implemented yet in GROMACS, e.g. writing 
energy data and/or other custom data. In a future version of GROMACS the 
TNG format might be made the default format, but it is not tested enough 
yet.

Best Regards,

Magnus
