If the angles change from the value in the data tables after you run
runpf(), then it just means that the initial data is not a steady state
solution to the AC power flow, and therefore such data is meaningless.
There is no "before this shift has happened".

Dear sir,
I am doing some research and for that I need the value of voltage
angles at different buses. when I use runpf() as you know, the angles
are kind of shifted as slack bus angle is 0 and the others are shifted
to that value.
But I need the values of angles before this shift has happened.
Which part of the code I need to manipulate to get there?
I would truly appreciate your consideration,
Best,
Hanie
