Hello Everyone,

ambconv.tgz (
http://www.gromacs.org/Downloads/User_contributions/Other_software)  tool
exists for converting Amer input files into the ones for Gromacs. Now, it's
README-eng file says that two Amber input files ( .atop (topology)  and
.rst (coordinates) ) are needed to generate input files for Gromacs.
Corresponding file formats in current Amber version are .prmtop and .inpcrd
respectively. Are these formats, just like older ones, exactly compatible
with this tool? If not, are there other tools to convert Amber input files
into the ones for Gromacs?

If this tool can be used, is the condition of removing all water before
applying this tool mandatory?

Thank you.
