[gmx-users] my problem when I use the g_rdf

[Hanming]

Dear All, 

I want to calculate the density of my globular molecules in order to
confirm that the density of the molecule is uniform,i.e.,the density of the
core part is the same as the other part. When I use g_rdf -com , I am
afraid the error will be big when the mass is divided by the small volumn
in the core part. Any one can give you some advice to deal with this
problem? 

Thanks a lot, 

Ming
