In 'final_coordinates_444.out' the cell parameters are listed as in the file *.in of Quantum Espresso (each line is a cell vector).
This structure is obtained after a (4x4x4) kpoint-grid geometry optimization of the structure of t-LGPS published in 
"Ong, S. P. et al. Phase stability, electrochemical stability and ionic conductivity of the Li10±1MP2X12 (M = Ge, Si, Sn, Al or P, and X = O, S or Se) family of superionic conductors. Energy Environ. Sci. 6, 148–156 (2013)."
