SCF
1. move to "scf" folder
2. do "mpiexec -n 1 ../../../../bin/phase"
3. after a few tens of seconds, SCF calculation will end.
4. be sure, "nfcharge.data" is generated.

DOS
1. move to "dos" folder
2. do "mpiexec -n 1 ../../../../bin/ekcal"
3. after a minute, DOS calculation will end.
4. be sure, "dos.data" is generated.
5. in order to draw a graph, do
   "../../../../bin/dos.pl dos.data -erange=-10,10 -with_fermi"
6. do "evince density_of_states.eps"

BAND
1. move to "band" folder
2. do "mpiexec -n 1 ../../../../bin/ekcal"
3. after a minute, BAND calculation will end.
4. be sure, "nfenergy.data" is generated.
5. in order to draw a graph, do
   "../../../../bin/band.pl nfenergy.data ../../../tools/bandkpt_bcc_ghnpgn.in -erange=-10,10 -with_fermi"
6. do "evince band_structure.eps"
