[gradsusr] Control File Issues for HDF5 file

[Govind Jha]

Dear Sir,
Greetings
I am trying to open HDF5 file from GPM IMERG file( 3B-HHR.MS.MRG.3IMERG.20170101.0000.V06A.HDF5) using GraDS version(2.0.2.oga.2). The grads control file is as follow:

DSET ^3B-HHR.MS.MRG.3IMERG.20170101.0000.V06A.HDF5
DTYPE hdf5_grid
TITLE IMERG sample
UNDEF -9999.9
XDEF 3600 linear -179.95 0.1
YDEF 1800 linear -89.95 0.1
ZDEF 1 levels 1 1
TDEF 1 linear 00:00Z01jan2017 30mn
VARS 5
/Grid/HQprecipitation=>HQp 0 x,y HQ precipitation
/Grid/IRprecipitation=>IRp 0 x,y IR precipitation
/Grid/precipitationCal=>Calp 0 x,y cal precipitation
/Grid/precipitationUncal=>Uncalp 0 x,y uncal precipitation
/Grid/randomError=>error 0 x,y random error
ENDVARS
When I open this file in grads. It successfully works. But While trying to display a variable called calp is shows the following error:
open imerg17.ctl
