effective potential difference measurement from a loop run

[Mausumi Chattopadhyaya]

Even after calculating effective potential in a loop over a range of bias I could not extract potential difference between any two points for a given bias. Kindly suggest me the correct script file so that I can estimate it at each voltage from the .nc file generated in the loop calculation.
