Dear Emanuele,
I think tutorial 1 will show you what you need. http://alps.comp-phys.org/static/tutorials2.1.0/dmrg-01-dmrg/spin_one_half.p... 'History' of measurements are available under the observable names: Iteration Energy Iteration Entropy Iteration Truncation
Once you loaded the datasets in python you can them print them, or save in some separate file if you wish.
Cheers, Michele

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.
