 # Exchange statistics
-When a file name is provided as input, an exchange file for each mpi is created. For respective step accepted and rejected attempts of exchange direction are recorded. 
-If the tempering move was not accepted, the number -1 is recorded. When the tempering move is accepted, the number of the interchanged mpi is recorded. 
-For example, in the exchange file for mpi2 an accepted temper move with mpi3 will record a 3, meaning the mpi's `2 <-> 3` etc. 
-In faunus/examples/temper there is a notebook "temper\_exchange\_statistics.ipynb" illustrating how this aquired data can be used to study how the mpi's are exchanged.
