Hi Chen, Ahai,
You don't need to fix a temperature when you run fulldiag but should specify the temperature only later when running fulldiag_evaluate. Have you tried that?

Dear all ALPS users
I want to calculate the density distribution of hubbard model with external potential in finite temperature using the "fulldiag" command, the main parameters are
......... t=1.0 CONSERVED_QUANTUMNUMBERS="Sz,Nup,Ndown,N" MEASURE_LOCAL[n_density]=n MEASURE_LOCAL[n_up]=n_up MEASURE_LOCAL[n_down]=n_down {T=1.0} {T=10.0}
It can get different thermodynamic quantities (e.g. free energy, specific heat) in different T, but the quantities I defined above keep the same in the two tasks.
I can't find the problem in this test. Any help would be appreciated.... Thanks.
