Francois has brought up several important points that you need to consider
when trying to design your residue.
I'll add that what you are doing is very similar to what is done in the
tutorial A1 that you can find on the amber site.
In this tutorial a dye is attached to DNA using a C6 type linker as is
commonly used in DNA synthesis. This should provide a good starting point
