[ncl-talk] Dataset required

[Soma Roy]

When I am running the script "vegland_1.ncl" as it is with the attached
dataset, I am getting the following error messages at run time;

fatal:_NhlUseWorkspace: dynamic memory allocation error
fatal:ContourPlotDraw: error reserving cell array workspace
fatal:ContourPlotDraw: draw error
fatal:ContourPlotDraw: draw error
fatal:PlotManagerDraw: error in plot draw
fatal:_NhlPlotManagerDraw: Draw error
fatal:_NhlUseWorkspace: dynamic memory allocation error
fatal:ContourPlotDraw: error reserving cell array workspace
fatal:ContourPlotDraw: draw error
fatal:ContourPlotDraw: draw error
fatal:PlotManagerDraw: error in plot draw
fatal:_NhlPlotManagerDraw: Draw error

Any direction to overcome this error?

Thanking you,
Soma
