I am performing some XANES simulations of site distortion in ZnO, and found some problems to change atoms position and run atoms. I want to know if is the same to change the atoms position of the ipot0 in the feff.inp file.
I am not sure I quite understand the question, but ... The central atom does not need to be at (0,0,0) in the feff.inp file. Atoms puts it there for the convenience of the human reading the feff.inp file, but that is not a requirement. It also does not need to be the first item in the atoms list.
