[gradsusr] HDF5 control file help

[Jennifer M Adams]

Hi, Joyce —
The first thing to try is set up aliases for those variable names, which are not GrADS-compliant. Something like this:
   Grid/precipitation=>p 0 y,x precipitation
   Grid/probabilityLiquidPrecipitation=>lp     0 y,x   liquid precip

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
