Unable to generate input for the real time post processing

Dear Developer,
I would like to see the optical spectrum from the real time simulation. But the input using ypp_rt is not generated. I tried the command line option ypp_rt -t which was working for earlier version. What is the new command to generate the input of post processing of real time calcualtion in version 5.
Regards,

With yambo 5.0 the syntax is
Code: Select all
ypp_rt -rtplot X -F inputfile_name.in
You can also use the shorter version
for the help

Dear sir,
Thanks a lot for the quick reply. One more question I will ask related to real time simulation using TD-BSE. There is an output file output.carriers in which 3rd and 4th coloumn is written as
dN_hole and dN_elec . Could you tell me what it stands for.
# Time[fs] d(N_hole-N_elec) dN_hole dN_elec

It contains
Code: Select all
n_v(t) = sum_{n in v,k} (1-rho_nnk(t))
n_c(t) = sum_{n in c,k} rho_nnk(t)
i.e. the number of carriers (holes in valence / electrons in conduction) injected in the system due to the pump.
Be aware that the identification of such number with the total number of carriers is exact at the IP level and it is a good approximation as long as valence and conduction are well separated.
You can find more info here:

Dear sir,
thank you for the reply. I will go through the paper and try to reproduce the result and post the difficulty if I face.
