[gmx-users] amber and vsites

[Erik Marklund]

Hi,

I'm trying to get vsites working for my DNA decamer with ffamber03. I've 
added the following to ffamber03.ddb,

[ NH2 ]
; N2-CA in Adenosine/Guanine
amber99_38 planar

but pdb2gmx adds no virtual sites to the adenosines/guanines. What am I 
missing here?
