projgen
The setup of the proj file by hand can be rather cumbersome for huge systems,
because the initial projections for every atom in the unit cell, for which
MLWFs should be constructed, need to be specified.
Consequently, the following procedure may be more convenient:
Specify the key projgen
in the wannier jobList in the inp.xml file
and write down the
projections for the chemical symbols in the file projgen_inp
using a simplified notation.
