Hi Dac,
I tested "set default nocenter on" in tleap, but the output solvated
protein coordinates are still different from the original one.
Could you help to check?
Here is the commands I used:
tleap -f tleap.in
ambpdb -p fxa.prmtop -c fxa.rst7 > fxa_solv.pdb
#compare fxa.pdb and fxa_solv.pdb in PyMOL
