[AMBER] binding free energy- error calculation doubt

Sir,

Below is the result i got for a receptor ligand system in mmpbsa
binding energy calculation. enthalpy and entropy parts. Could any one
help me, how to calculate the uncertainty part in delta G from this
result?

Also how could i include the uncertainty or error in hbond distance
(receptor ligand hbond) calculation obtained using ptraj on a complex
trajectory. Could i include error if i calculate hbond distance on a
single representative structure in vmd?
