Hi all,

I'm trying to use virtual sites in a DNA in water simulation with Charmm27
force field. When feeding my pdb to pdb2gmx with this cammand "pdb2gmx -f
my_DNA.pdb -vsite hydrogens', it gives me this error

Fatal error:
No vsite database NH2 entry for type NN1

Is this not implemented or did I miss something? Any input would be
appreciated.

Regards
Terry
