To All
Hello - again - 2nd, question - this time about analysis nudging?
I have the analysis files in proper directory and when I run the real.exe - wrf.exe sequence, it executes properly. 
However when I turn in the fdda by using the following namelist fragment 

&fdda
 grid_fdda                           = 1,
 gfdda_inname                        = "wrffdda_d<domain>",
 gfdda_interval_m                    = 360,
 gfdda_end_h                         = 24,
 io_form_gfdda                       = 2,
 fgdt                                = 0,
 if_no_pbl_nudging_uv                = 0,
 if_no_pbl_nudging_t                 = 0,
 if_no_pbl_nudging_q                 = 0,
 if_zfac_uv                          = 0,
  k_zfac_uv                          = 10,
 if_zfac_t                           = 0,
  k_zfac_t                           = 10,
 if_zfac_q                           = 0,
  k_zfac_q                           = 10,
 guv                                 = 0.0003,
 gt                                  = 0.0003,
 gq                                  = 0.0003,
 if_ramping                          = 1,
 dtramp_min                          = 60.0,
 /

I get the following error in the rsl.out.0000 files
.
.
 D01 Analysis nudging for wind is turned on and Guv=   0.3000E-03
 D01 Analysis nudging for temperature is turned on and Gt=   0.3000E-03

 -------------- FATAL CALLED ---------------
 FATAL CALLED FROM FILE:  input_wrf.b  LINE:     491
  ... Could not find matching time in input file
 -------------------------------------------

The Error is always on the 1st output.
Any cluse of what I am doing wrong - or is there additional documentation besides the
