[gradsusr] HDF5 control file help

[Meyerson, Joyce]

Hi Users,

I have a hdf5 data file from NASA's Global Precipitation Measurement project and I'm having trouble writing the control file. I don't know what I'm doing wrong. Any help would be greatly appreciated. The error I'm getting is 

> open test.ctl
Open Error:  Invalid variable record
 --> The invalid description file record is: 
 --> Grid/precipitation                0 y,x   precipitation
