Error for real-time example

Dear all,
I used Yambo-4.3.2 to do the rt calculations as depicted in yambopy example. When I generate ELPH using ypp_ph, I got an error as:

All the input are same as in example/Si in yambopy.

Tanks!

Dear Wang,
electron-phonon scattering during real-time simulations is not yet available in the GPL version of yambo.
You can only do real-time simulations with static electron-electron self-energies

This means that the code to run section 4 in the yambopy example is not yet available.

Best,
D.
