[ferret_users] Composite of MJO phases



Dear Ferret users,
I have 11 years netCDF data which is the output of Regcm4 Model. I want to make a composite of precipitation data that have the same MJO phases from that file. Let say MJO phase 1 occurred on (yyyy-mm-dd):
20000926
20000927
20001110
20001111
20001112
20021211
20021212
20021213
...
...
20100115
20100116
...
...

I put the list on a .txt file. So, in the end i will have 8 netCDF file that content the same MJO phases on 11 years. Any advice to do this composite? Thank you in advance.

Here is the description of my data (RegCM4 output):
    XAXIS = 103 ;
    YAXIS = 95 ;
    TIME = UNLIMITED ; // (2928 currently)
    bnds = 2 ;
variables:
    double XAXIS(XAXIS) ;
        XAXIS:units = "DEGREE" ;
        XAXIS:point_spacing = "even" ;
        XAXIS:axis = "X" ;
        XAXIS:modulo = 360. ;
    double YAXIS(YAXIS) ;
        YAXIS:units = "DEGREE" ;
        YAXIS:point_spacing = "even" ;
        YAXIS:axis = "Y" ;
    double TIME(TIME) ;
        TIME:long_name = "time" ;
        TIME:calendar = "gregorian" ;
        TIME:units = "hours since 1949-12-01 00:00:00" ;
        TIME:bounds = "TIME_bnds" ;
        TIME:axis = "T" ;
    double TIME_bnds(TIME, bnds) ;
    float PR(TIME, YAXIS, XAXIS) ;
        PR:missing_value = -1.e+34f ;
        PR:_FillValue = -1.e+34f ;
        PR:long_name = "PRCV[GXY=NEWGRID@ASN]" ;
        PR:history = "From MIT_20_Sumatera_SRF.2000010100" ;




Kind regards,
