Use the code

Once the executable exc created (it should be in \$prefix/bin after the make install) you can run the EXC code.

What you need is:

• The ground state calculation output = kss file.
• GW corrected energy = gw file.
• Screening function = em1 file.
• An input file (see below)

Then execute: exc -k file.kss -e file.em1 -g file.gw -i input > exc.log &

Defaults:
The commmand exc > exc.log & will look for a default in.kss and in.em1 files in the current directory. An input file exc.in will be also searched in the current directory.
