Dear ALPS users,
I am running the DMRG algorithm with python. I don't understand where the energy/entropy/trunc. err. history is recorded. 
I would like to set up a way to create three different files with the history of these three quantities.
Is there a way to do that?

Many thanks.
Kindest regards.
