CDO

Dar CDO users,

To extract the region, I run the command
cdo sellonlatbox mon_03.nc new.nc

cdo sellonlatbox : Enter western and eastern longitude and southern and northern latitude > 59,68,5,38

But it's not working, I received the warning as
Warning (genlonlatbox_reg) : Allocation of 0 bytes! [ line 332 file Selbox.cc ]
Segmentation fault: 11

#####
The variable names of the attached file are given as
-1 lat latitude [degrees_north]
-2 lon longitude [degrees_east]
-3 Snow_Cover_Monthly_CMG Monthly snow cover extent, 5km [none] #####

and the grid structure is given as

1. gridID 1 #
   gridtype = lonlat
   gridsize = 3600
   ysize = 3600
   yname = YDim_MOD_CMG_Snow_5km
   ylongname = "latitude"
   yunits = "degrees_north"
   yfirst = 89.975
   yinc = -0.0499999999999972 #
2. gridID 2 #
   gridtype = lonlat
   gridsize = 7200
   xsize = 7200
   xname = XDim_MOD_CMG_Snow_5km
   xlongname = "longitude"
   xunits = "degrees_east"
   xfirst = -179.975
   xinc = 0.05 #
3. gridID 3 #
   gridtype = lonlat
   gridsize = 25920000
   xsize = 7200
   ysize = 3600
   xname = XDim_MOD_CMG_Snow_5km
   xlongname = "longitude"
   xunits = "degrees_east"
   yname = YDim_MOD_CMG_Snow_5km
   ylongname = "latitude"
   yunits = "degrees_north"
   xfirst = -179.975
   xinc = 0.05
   yfirst = 89.975
   yinc = -0.0499999999999972

please provide some information on that (How to extract region using sellonlatbox)

Thank You
