Dear All, I'm using the DMRG code in the alps-2.1.0d1-r6050 version and I would like to resume some simulations after they have finish properly. I want to increase the number of sweeps previously defined (sometimes from 3 to 4) then when it finishes I just add the parameters to my python script to start from the sweep 3. When I ran the script it stops due an error of *.dat files not found. Where ALPS save the *.dat files to resume from another simulation? I tried to find them by myself without success. Should I give another parameter to let ALPS knows I want to save that files? Giovanni Ramirez-Garcia
