[gmx-users] reduced units

[Pengzhi Zhang]

Hello there, 

I'm a gromacs newbie. I am using gromacs function g_anaeig to do principle
component analysis. I use coordinates (converted to be .trr files for
gromacs) and topology from amber. I know that gromacs works with units like
nm, kJ/mol etc, while amber with angstrom. Does anyone know that when
gromacs read the coordinate files, whether it assumes the values are in nm
or in angstrom (if so, gromacs converts them by itself to nm without telling
us)? 

Thanks for any help. 

Sincerely,
Pengzhi
