triqs.gf.tools.read_gf_from_txt
- triqs.gf.tools.read_gf_from_txt(block_txtfiles, block_name)[source]
Read a GfReFreq from text files with the format (w, Re(G), Im(G)) for a single block.
Notes
A BlockGf must be constructed from multiple GfReFreq objects if desired. The mesh must be the same for all files read in. Non-uniform meshes are not supported.
- Parameters:
block_txtfiles (Rank 2 square np.array(str) or list[list[str]]) –
The text files containing the GF data that need to read for the block. e.g. [[‘up_eg1.dat’]] for a one-dimensional block and
- [[‘up_eg1_1.dat’,’up_eg2_1.dat’],
[‘up_eg1_2.dat’,’up_eg2_2.dat’]] for a 2x2 block.
block_name (str) – Name of the block.
- Returns:
g – The real frequency Green’s function read in.
- Return type:
