Hi all,
I didn't get an answer when I asked before about this, but I thought that I would try again. In DMRG the common practice is to use the truncation errors at different MAXSTATES to extrapolate the energy. However, the dmrg code currently does not write out the truncation error to a file. Is there a way to have the dmrg program write this out for the last sweep? Even just one value from the last sweep or the mean would be useful. I know that the truncation error for each step is written out to the screen, but it is rather inefficient to run one batch at a time and then copy down the truncation error. I really appreciate the help that I have received thus far and am very grateful for the ALPS collaboration overall. I'd appreciate any hints you might have regarding this.
Thanks, Justin Peel
