<div> </div>
<div>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?</div>

<div><u>GRADS COMMAND:</u> d consecutive_dry_days_index_per_time_period</div>
