[gradsusr] problem in openning a *.NC file in grads

[Ismaila Diallo]

Dear 

i've concatenated some file with nco command by using the formula:
ncrcat input[123456789].nc output.nc

output.nc is a daily file for 0 year with many parameter at different levels.

Therefore whe i'm trying to open it with to version of grads: grads 1.9 and 
grads 2.07 but i get the following error: 


sdfopen ATM_.2000_DAY.AVG.NC 
Scanning self-describing file:  ATM_.2000_DAY.AVG.NC
nc_open failure:
Value too large for defined data type
ATM_.2000_DAY.AVG.NC does not exist or is not a netCDF file.

Couldn't ingest SDF metadata.
If this was an HDF-SDS file, try gradshdf.

for opening i've tested xdfopen but i got the same error. 

But when i check the file structural with ncdump that work well.

Could someone suggest me how to do to open the file with grads.

Sincerely
Ismaila
