Re: [netcdf-java] Creating unlimited dimension


Thanks Jeff,

Seems to work if I create thusly:

Dimension timedim = ncout.addDimension("TIME", 0, true, true, false);

though I'll try the addUnlimitedDimension method, too.

Trying to get faster read times with the version 2.2.22 over opendap.

Cheers,
Chris

Hi Chris,

I believe you need to do something like:

Dimension timedim = ncout.addUnlimitedDimension("time");

See the last example at:

Hope that helps,
Jeff

I'm trying upgrade to netcdf 2.2.22... I used to create a netcdf file with
unlimited time dimension using:

        Dimension timedim = ncout.addDimension("TIME",-1);

but now I try,

        Dimension londim = ncout.addDimension("LON", isize);
        Dimension latdim = ncout.addDimension("LAT", jsize);
Dimension timedim = ncout.addDimension("TIME", 0, true, true, true); 
        Dimension[] dim3 = new Dimension[] {timedim,latdim,londim};
        ncout.addVariable(varName[varNum], float.class, dim3);


and I get:
java.lang.IllegalArgumentException: Unknown dimension can only be used in 1 dim 
array

gov.noaa.tsunami.cmi.LinCombModule.downloadFile(LinCombModule.java:325)

Any ideas?  I can't find a simple example for creating with unlimited
dimension...

Cheers,
Chris
