Two problems of the PDOS calculation in ab intito MD

[Bin Gu]

Dear CP2kers: 

I am using the cp2k ADMM methods to run an MD simulation.  I was puzzled 
with two problems at present. 

*1. about the data print. *

When I try to print out the PDOS of several atoms using: 
---------------------------
       &PDOS
         ADD_LAST  SYMBOLIC
         NLUMO  20
         &EACH
           MD  10
         &END EACH
         &LDOS
           LIST  991..997  
         &END LDOS
       &END PDOS
--------------------------------
in the DFT Print module, it works! 
Unfortunately,  t*he output data of PDOS will always cover the data of the 
former step*, in the same file named : ALPHA_list1-1.pdos. 
*Only the last md step is remained.  *
How can I get the records of the PDOS of each step? 

*2. about the calculation of PDOS in ROKS.*

When I try to calculated the system with excess charge under the condition 
of ROKS, *the calculation will always stopped with : *
-------------------

the *output files will contain the ALPHA_list1-1.pdos, with single occupied 
as*

-------------------------------------
I am wondering  Is there any conflict in the ROKS with PDOS?


Many thanks for any response and comments.
