errors in DMFT CTQMC solver

Post by pipidog » Thu May 25, 2017 2:37 am

Hello all,

I performed a DFMT calculation with CTQMC solver. The calculation looks fine without any error message in Abinit.
However, when I run OmegaMaxEnt, I always got errors as shown below.
I've attached my input files (a test run, so set U=0). Can anyone give me any suggestion?


data file: Gtau.dat
data file loaded
bosonic data (yes/[no]): no
imaginary time data (yes/[no]): yes
interactive mode ([yes]/no): no
show optimal alpha figures ([yes]/no): no
show lowest alpha figures ([yes]/no): no
show alpha dependant curves ([yes]/no): no


fermionic Green function given in imaginary time
For a Green function given in imaginary time, the first two moments are required to obtain the Matsubara frequency Green function.
The program will try to extract those moments from the behavior of the Green function around tau=0 and tau=beta.
Number of imaginary time slices: 300
-G(0)-G(beta): 1
Not enough moments provided to define the real frequency grid. The program will try to extract moments from G(tau) around tau=0 and tau=beta.
no errors provided
using a constant error

Could you please post your Green's function file Gtau.dat ?
Best regards
