Hi George,

Using Leap in Amber, you can get a topology file (*.prmtop) and a
coordinate file (*.prmcrd). That is all you need. Then in the conf
file for namd:

amber on # Specify this is AMBER force field
parmfile *.prmtop # Input PARM file
ambercoor *.prmcrd #input coordinate file

You can find detail description in the namd manual.
