Thank you for your help. I tried your ctl file in grads-2.0.1 and
opengrads-2.0.1.oga. (I have used the executable binary files from their
websites) But in both of them I got the following error
*_______________________________________*
_______________________________________
ga-> open
tesl3hdo.ctl
Scanning description file: tesl3hdo.ctl
Open Error: Invalid variable record
--> The invalid description file record is:
--> /HDFEOS/GRIDS/NadirGrid/Data~Fields/HDO=>hdo
15 x,y,z
The data file was not opened.
__________________________________________________________________________
Please help me in this regard
Please explain the procedure of creating ctl file from he5 files.
with regards,
midhun
