[gradsusr] 回复： netcdf file written with GDAL, when opened with a ctl file , shows constant field

[Syed Ahsan Ali]

Yes I tried for single ctl file first which also gave following error.
Although the variable band1 is present in the netcdf file and is being
displayed when file is opened using sdfopen

Error: Variable band1 not in netcdf file
Data Request Error:  Error for variable 'band1'
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = band1
