[ALPS-users] how to retrieve output datas in DMRG

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. -- Emanuele Levi emanuele.levi@gmail.com
