[gradsusr] Re : Viewing Climate Indices Created with CDO

Hi,

I guess it's because the variable name is too long. I suggest you do "q file" and whatever variable name it returns you display it.

Hope this will help
cheers

Hi, I am a beginning user of GRADS and would really appreciate some help. 
 
I took a model run and performed an operation using CDO that gave me the number of consecutive dry days for each grid box for the time period selected. I then open this in GRADS. When I try to view the results on a map GRADS keeps giving me an error that indicates index is not a variable name. I tried to open the file in XCONV to modify the variable name - but XCONV won't open the file. As a beginning user my skill set to solve these problems is quite limited. Does anyone know what I should do?
 
GRADS COMMAND: d consecutive_dry_days_index_per_time_period
GRADS RESPONSE
Syntax Error:  Invalid Operand
  'consecutive_dry_d' not a variable or function name
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = consecutive_dry_days_index_per_time_period
