Writing drifter data to multiple files in datablock.xml

Question

Hi - I am running simulations with large numbers of drifters. If I write data for all drifters to a single file, this file ends up rather large and difficult to work with.

I could write the output for each drifter to a separate file using

 <filename>drifter1.nc</filename>

  <drifterNumber>1</drifterNumber>

But with several thousand drifters, that's a lot of files!

Is there a way to write multiple drifters to files, or is it a choice between everything in one file, or everything in a separate file?

I tried   <drifterNumber>1:1000</drifterNumber> but get an error message that 1:1000 is not a number.

Thanks

From page 135 of the user maual

To specify the output of a drfiter file the Drifter section is used. More than one Drifter section can be given to output drifter data to different files. The Drifter section must contain the filename tag which gives the name of the unf file and either a <outputAll>true</outputAll> line or one or more drifterNumber tags. The drifterNumber tags give the drifter to output (1-ndrifters).
