  In RF2 lesson, when running the example, the input file sets ndset=10 using 
ngkpt=4x4x4. But if i am not satisfied with the phonon band structures, what 
can i do except set higher ecut and more stringent tol*** variables?
 
  I want to do more accurate GS calculatio, so I tried to set : 
    ngkpt1  6 6 6
    ngkpt2  6 6 6
    ngkpt3  6 6 6
    ngkpt   4 4 4
  but the program failed when the 4th process starting? Why? 
  Does that mean the GS calculation should have the same 'ngkpt', consistent 
with phonon band structures calculation? 

  Can anyone get me some help??

----- Another problem troubled me a lot:
  When i follow the steps after 'tutorial on analysis tools', error appeared 
in during installing the ElecStruc_OpenDX:

 cc  -L/export/home/qgr/program/dx/lib_linux -o AddSticks userAddSticks.o 
AddSticks.o -fPIC -shared  
/usr/bin/ld: userAddSticks.o: relocation R_X86_64_32S against `a local

Thanks in advance~!
