Error in displaying TRMM 3B42 hdf data file

[Zhong Liu]

You're right. I couldn't access my ctl file yesterday. Here is the
correct one,

DSET ^3B42.041118.18.6.HDF
DTYPE hdfsds
TITLE This is only a test
UNDEF -9999.90
XDEF 1440 LINEAR -179.87500000 0.25000000
YDEF  400 linear  -49.87500000 0.25000000
ZDEF 1 LEVELS 1 1
TDEF 1 LINEAR 18Z18nov2004 3hr
VARS 2
precipitation=>pcp    1  z,x,y Precipitation
relativeError=>err    1  z,x,y Error
ENDVARS

If you have TRMM related questions, please let me know.

Cheers.

As Dr Mahakur pointed out, " z,x,y you can use for  for level dependent (zdef >1) variables and t,x,y for (zdef=1)and tdef=1 or more. It depends upon the data.". In my case, zdef=1 and I need to put it as t,x,y (not t,z,x,y).
