Hello all,

I calculate diffusion constant for each individual molecule
using g_msd and -mol option.
There are some negative values in the output file.
Diffusion constant is always positive value, isn't it?
I don't know how negative value is calculated.

I am using gromacs 3.2.1.

give me some advice, please.

Thanks in advance.
