Hi everybody.

I'm trying to open an hdf file using xdfopen.
I've tried to follow the instructions but it doesn't works.
The results were:

gradshdf
Grid Analysis and Display System (GrADS) Version 1.8SL11
Copyright (c) 1988-2001 by Brian Doty

Issue 'q config' command for more information.
Landscape mode? (no for portrait):
GX Package Initialization: Size = 11 8.5
ga-> xdfopen le_LRDC.ctl
Scanning Descriptor File:  le_LRDC.ctl
udunits(3): syntax error:

Alleged time dimension (from TDEF) is not an SDF dimension.  Cannot continue.
Time dimension name is:
Local_Hour
.
Data file /home/marco/lis/dados/LISOTD_LRDC_v1.0.hdf was not successfully
opened & parsed

My ctl file :

DSET ^/home/marco/lis/dados/LISOTD_LRDC_v1.0.hdf
TITLE Teste de leitura de hdf
XDEF Longitude 144 LINEAR -178.75 2.5
YDEF Latitude 72 LINEAR -88.75 2.5
TDEF Local_Hour 24 LINEAR 00Z01JAN1996 1hr
vars 1
LRDC_COM_FR=>flrt   24 99 Combined Flash Rate Climatology
endvars

The result of hdf ncdump applied to the hdf file :

netcdf LISOTD_LRDC_v1.0 {
dimensions:
        Latitude = 72 ;
        Longitude = 144 ;
        Local_Hour = 24 ;
        DE_By_Threshold = 3 ;
        DE_Local_Hour = 24 ;
        DE_Latitude = 72 ;
        DE_Longitude = 144 ;

variables:
        float LRDC_COM_FR(Latitude, Longitude, Local_Hour) ;
                LRDC_COM_FR:valid_range = 0.f, 0.023581842f ;
                LRDC_COM_FR:long_name = "Combined Flash Rate Climatology" ;
                LRDC_COM_FR:units = "Flashes/km^2/hour" ;
                LRDC_COM_FR:_FillValue = 0.f ;

.....
data:

 Local_Hour = 0.5 , 1.5 , 2.5 , 3.5 , 4.5 , 5.5 , 6.5 , 7.5 , 8.5 , 9.5 ,
    10.5 , 11.5 , 12.5 , 13.5 , 14.5 , 15.5 , 16.5 , 17.5 , 18.5 , 19.5 ,
    20.5 , 21.5 , 22.5 , 23.5  ;

Any ideas about these problems?

Thanks in advance.
