Dear all, I am facing a problem during the postprocessing of the RegCM-4.0. Firstly, I run sigma2p successfully but when I am trying to run the average part, the terminal displays the following error:  Calculate the daily mean of   ICBC        2004           2                                ICBC        2004           3  Calculate the daily mean of ICBC_P        2004           2                              ICBC_P        2004           3 At line 1635 of file average.f90 (unit = 10, file = './input/test4_ICBC_P2004030100') Fortran runtime error: Non-existing record number The postproc.in file is the following: &shareparam  iy   = 225,  jx   = 225,  kz   =  18,  nsg  =   1,  ntr  =  10,  i_band = 0,  ibyte  = 4,  igrads = 1,  Path_Input  = './input',  DomainName = 'test4'  Path_Output = './output', / &sigma2p_param  np = 11,  plev = 1000.,925.,850.,700.,500.,400.,300.,250.,200.,150.,100.,  s2p_ICBC = .true.,  s2p_ATM  = .true., / &dateparam  idate0 = 2004010100,  idate1 = 2004020100,  idate2 = 2004032000, / &averageparam  day_ICBC   = .true.,  day_ATM    = .true.,  day_RAD    = .true.,  day_SRF    = .true.,  day_SUB    = .false.,  day_CHE    = .false.,  day_ICBC_P = .true.,  day_ATM_P  = .true.,  mon_ICBC   = .true.,  mon_ATM    = .true.,  mon_RAD    = .true.,  mon_SRF    = .true.,  mon_SUB    = .false.,  mon_CHE    = .false.,  mon_ICBC_P = .true.,  mon_ATM_P  = .true., / &regridparam  regDOMAIN   = .true. ,  regICBC     = .true.,  regOUT_HEAD = .true.,  regATM      = .true.,  regSRF      = .true.,  regRAD      = .true.,  regICBC_P   = .true.,  regATM_P    = .true.,  xminlon = -9999.0,  xmaxlon = -9999.0,  xminlat = -9999.0,  xmaxlat = -9999.0,  ddeg = 0.5, / What am I doing wrong?
